Bridge Mode Problems?

Connected my new AEBS gigabit model one week ago to our existing home network with the AEBS in bridge mode. All worked fine for 7-days but we lost internet connection yesterday. The Belkin router needed to be reset and Belkin support says its because the AEBS is set up in bridge mode.
Setup is: DSL modem (providing PPoE to ISP) connected to Belkin 4-port wired ethernet router WAN port and AEBS WAN port connected to "regular" port on the Belkin router. DSL modem and wired router are downstairs (in home office) and the AEBS is upstairs (for full house wireless coverage).
I need to maintain the current physical locations of the hardware. Do I need to change the setting of the AEBS from bridge mode? What other setting(s) would work?
Thanks

Hello MacsNMore. Welcome to the Apple Discussions!
Setup is: DSL modem (providing PPoE to ISP) connected to Belkin 4-port wired ethernet router WAN port and AEBS WAN port connected to "regular" port on the Belkin router. DSL modem and wired router are downstairs (in home office) and the AEBS is upstairs (for full house wireless coverage).
This looks like a good setup. I assume that your Belkin router is providing NAT & DHCP services...correct?
I need to maintain the current physical locations of the hardware. Do I need to change the setting of the AEBS from bridge mode? What other setting(s) would work?
Having the AEBSn in bridge mode would be the most appropriate configuration for your network setup.
Let's double-check your AEBSn's settings...
Temporarily connect your computer directly (using an Ethernet cable) to one of the LAN ports of the AEBSn, and then, using the AirPort Utility in Manual Mode, check these settings:
Internet - Internet Connection
o Connect Using: Ethernet
o Configure IPv4: Using DHCP
o IP Address: <provided by your ISP>
o Subnet Mask: <provided by your ISP>
o Router Address: <provided by your ISP>
o DNS Server(s): <provided by your ISP>
o Domain Name: <provided by your ISP>
o DHCP Client ID: (optional)
o Ethernet WAN Port: Automatic (Default)
o Connection Sharing: Off (Bridge Mode)

2 Airport Express - Bridge Mode problems

Hi,
Apologies if this has been covered elsewhere but I've been searching and can't find a solution to the problem.
I have:
MacBook Air running Mavericks and Airport Utility
Old Airport Express set up to create a wireless network
New Airport Express set up as bridged
Our apartment is hardwired with LAN ports in the walls, so there is no need for a modem and there are no router conflicts etc. I'm aware of.
Everything is fine with the Old AE as it's been for years. When I connect the second AE which I want to set up in another room to extend the existing network it goes through all of the steps in the wizard OK but as soon as the second/bedroom AE completes setup and the light goes green the first AE in the living room drops out with orange flashing light and a "Conflicting DHCP Range" error. I barely know what this is, let alone how to resolve it. Whenever I find a community discussion I can find people talking about the same issue but no clear idea of how to resolve.
Any help would be massively appreciated.

Yeah fair comment, pretty remiss of me.
There was actually nothing wrong, but I was connecting the second AE to a LAN port with a cable as well. I mistook the drawings on the apple site for cable connections and assumed they all required it.
Just removed the Ethernet cable, ran set up again and was good to go.

EA4500 - bridge mode solved all my problems

For what it's worth, putting the EA4500 in bridge mode and using none of its capabilities solved all my access and stability problems.
My setup:
EA4500
Firmware Ver.2.1.39.145204
Bridge mode
Network topology:
comcast supplied cablemodem --- Cisco 871 -- Linksys EA4500
After nickel and diming my home networking for years, I found it's better to just spend the money and be done with it.
I went to this setup shortly before Cisco jettisoned Linksys (maybe Linksys would have been better off never having been bought in the first place, I don't know and that's a different discussion) in 2013 and I've had zero problems and 100% stability ever since.
The Cisco 871 can run for as low as under $100 and you are getting and enterprise-class router that runs Cisco IOS. It's well known, well understood and universally supported. If you ever wanted to learn about networking and Cisco IOS, this is probably one of the cheapest ways to do it. Downside is that the 871 only support 802.11b/g so I use the EA4500 with dual 2 & 5Ghz to support both my 802.11n 5Ghz laptops and newer smartphones and tablets and 2Ghz for the older stuff. Works great.

Thanks for sharing. Will try that in the future.

ACE problem - bridge mode - behind a firewall

Hello
We are having problems with one of you ACE context, this implementation was done by a supplier and I am trying to troubleshoot it.
The clients and the servers are on different subnets, there is a Nokia firewall in the middle. The firewalls are setup on a cluster.
Connecting to port 7072 is taking at least 30 seconds. If I move the server into the VLAN in front of the ACE, the connection is instant. So it does indicate a problem on the ACE.
The client IP is .99.11.
The VIP is .100.62 and the server node is .100.12.
Running the capture command I can see the following behavior:
1. The client initiates the connection to the ACE Vip
2. At the same time it looks like a second connection is initiated from the client to the server node
Please see attachment.
Is this a normal situation where the connection is duplicated?
Does this interface setup look correct?
Is the bridge mode the correct setup in this scenario?
interface vlan 10
bridge-group 2
no normalization
mac-sticky enable
access-group input PERMITALL
service-policy input VLAN10-INTER-MMPM
no shutdown
interface vlan 15
bridge-group 2
no normalization
access-group input PERMITALL
no shutdown
interface bvi 2
ip address 192.168.100.7 255.255.255.192

peer ip address 192.168.100.8 255.255.255.192
no shutdown
ip route 0.0.0.0 0.0.0.0 192.168.100.1
Many thanks,
Damian

Thanks for replying James,
I am sure I configured the capture only for VLAN10 which is in the VIP side.
But you are right, it looks like is showing both VLAN10 and VLAN15. So that is one of my theories out of the window! :)
This is a new installation, still on the testing stage. So it would be good time to make changes.
Do you normally implement a routed setup behind a firewall? Rather than a bridgedâ¦.
It is quite a small setup:
â¢ Traffic is coming from a separate local subnet
â¢ Traffic is not coming from the internet so it does not required a NAT
â¢ We need 1 VIP listening on two ports
â¢ The backend servers are four Linux boxes
Thanks again,
Damian

Problems with Bridge Mode - Please advise.

Folks I have my Time Capsule on our network in bridge mode to use it as a switch and wireless access point. Internet connectivity seems to keep having problems and I am not sure if my setup makes sense:
My Setup: Netgear DGN3500 Router (modem built in) ->Time Capsule (in bridge mode via ethernet) -> Network devices
Problems:
- Time Capsule TCP/IP has 169.xxx.xx.xx IP Address using DHCP, subnet is wrong (missing one "255" set) , router address is correct
- Netgear router sees Time Capsule connected with a proper IP address (192.168.1.xxx) in routing table
- flashing amber light due to airport not having a valid IP address even though I turned wireless off temporarily for the purposes of trouble shooting. I first just want to get ethernet working correctly
I've reset my router, the Time Capsule all settings, renewed DHCP Lease in Time Capsule...all the standard fanfare.
Any ideas folks or is this thing just done?
Tesserax if you're out there, please respond. I think you've addressed this as well, but I have no solution.

If my router is the DHCP server and my TC is in bridge mode (accepting DHCP info) shouldn't my TC be getting 192.xxx.x.xxx numbers and same subnet mask?
Yes. Have you power cycled the entire network as a troubleshooting step in this regard? If not, power everything down on the entire network, order is not important.
Start your modem first and let it run a moment by itself, then start the next router connected to the modem the same way. Start the Time Capsule the same way. Continue starting devices one a time the same way until the entire network is powered back up.
Additionally, if the TC is in bridge mode, can it serve other devices through the other LAN ports?
Yes. In bridge mode the ethernet ports are acting like a simple ethernet switch. Since they all behave like LAN ports in this configuration, try a different port on the Time Capsule for your connection from the switch to see if that helps.
I suppose I could tell my netgear to only give a range of addresses and the TC another range, but I didn't think I'd have to go through all of that.
I would not recommend that you do this. Even if you are able to avoid IP address conflicts, you'll have a Double NAT error on the network, at best slowing communications down. At worst, devices on one sub net will not be able to communicate with devices on the other sub net.
By the way I forgot to mention one part of my network - the switch (not the LAN one built into my netgear router). There's a 24-port
As a troubleshooting step, try bypassing the switch to see if that makes any difference in the performance of the TC. I like Netgear switches and have used them for years, but I've also had an occasional failure in several of their ethernet switches. It does happen.

Problems with Bridge mode at a hotel

Hi there,
I have my Airport Express (N) set up to create a wireless network, use DHCP, and be in Bridge mode. When I plug in the Ethernet cable from a hotel (where you are required to subscribe and pay for their service), I can use the internet from my laptop wirelessly without problems. However when I connect to wifi from my iPhone 3GS, it connects to the network, but prompts me to repay for another service. The site also states that the price is 'per computer'. I was under the impression that when a router was in Bridge mode, it was invisible to the hotel network, and you can share the internet connection with multiple computers, but somehow the hotel is detecting exactly that. Am I missing anything here?

Sorry, the hotel router is configured to charge you for each separate device that connects. In other words, if you connected with your computer and paid the fee, and then another person tried to connect their laptop, the hotel router sees another device and will charge for that device.
Bridge mode on the Express allows you to configure your computer so that the hotel router sees your computer as the connecting device. Bridge mode is the only setting that will work correctly to allow you to configure your Express.
Specifically, the hotel assigns an IP when you connect your computer, if you try to connect another device, it needs to assign another IP address. The hotel will charge you for each IP address.

AEBS in bridge mode: wired problems

Hello, I can't manage to setup AEBS to fit my needs.
Here's the situation:
There's a router/switch that provides net access (wired) to the flats in my building. It distributes IPs through DHCP (in the range 10.68.3.x).
Plug1 (office room): Mac Pro, wired connection
Plug2 (living room): AEBS (through LAN port)
AEBS LAN port: XBox 360
AEBS wireless: Powerbook
the AEBS is configured to be a client to DHCP and in bridge mode.
the Mac Pro, AEBS and Powerbook get correctly their config (in the 10.68.3.x range) but the XBox does not (169.254.240.x).
If I wire the powerbook to the AEBS and switch off airport, same thing, it loses its config and get a 169. address.
So basically, it seems it bridges between LAN and wireless but not between LAN/LAN.
I know i can get something working if i accept to have the MacPro on another subnet than the network after the AEBS (if i use DHCP/NAT with AEBS). But then I loose the possibility to share files between the two computers.
Another possibility would be to use a switch before the AEBS for the wired part of the network i guess, but i'd prefer not to add one more piece of hardware.
Does anyone went through this type of problems or setup? Or is it definitely not possible? Any clue will help.
PS: The final network would be more complicated if i get past this stage (WDS with Airport Express to cover the whole flat)

Arkhleyi, Welcome to the discussion area!
Plug2 (living room): AEBS (through LAN port)
Have you tried changing this to the WAN port?

Internet Problem with Time Capsule (Wi-Fi) and AT&T U-verse Motorola NVG589 (Bridge Mode)

I'm having a problem with my Internet connection. For some unknown reason it keeps cutting out every 5 min for about 5 seconds. The wi-fi signal doesn't drop or anything like that, just the internet connection stops working for a little bit and then its fine again (pages don't load, etc).
Here is my current set-up:
1. AT&T Motorola NVG589 - set to bridge mode as per instructions here http://www.dslreports.com/faq/17734 (followed instructions step by step)
2. Apple Time Capsule (latest model 2TB)
3. Motorola is connected to the Time Capsule through an ethernet cable.
I tried contacting AT&T and they just sent me a new Motorola router, I installed it, put it in bridge mode and still the same thing is happening.
I am thinking maybe there is some problem in settings or something. Airport Utility is showing everything in "green", no problems there.
Please let me know if anyone can help.

Ok, here is an update on how I decided to deal with the problem. I will include all of my troubleshooting step by step for easy reference.
1. At first I put the NVG589 into Bridge Mode and used the TC as the main wireless router. This didn't work as my connection kept dropping for no apparent reason.
2. Second, I tried to put the Time Capsule in Bridge Mode and connect it directly to NVG589. This didn't work as my connection would still lag out for 5 seconds about every 5 minutes.
3. Third, I bought an ASUS RT-AC87U Wireless AC2400 Dual-band Gigabit Router to try and substitute the TC in previous steps and see if it helps. Same problem persisted when I put the NVG589 into Bridge Mode and RT-AC87U as the main router as well as RT-AC87U into bridge mode and NVG589 as the main router. The problem was exactly the same as when I tried using TC initially so my conclusion was this is NVG589's fault of being not compatible with other wireless routers.
4. I looked around everywhere and came up with the only feasible solution possible (for me at least):
Currently I use NVG589 as my main wireless router. I works pretty well and even though it doesn't have the specs of TC or the ASUS router my WI-FI connection is pretty fast and stable. In order to have Time Machine wireless backups, I purchased a Western Digital My Cloud Drive that is connected directly to the NVG589. Everything seems to sync and work well together.
I know this is not the ideal solution most people are looking for. But it works for me. Patiently waiting for AT&T to start offering NVG599 (http://www.dslreports.com/forum/r28967809-NEW-U-verse-Gateway-Motorola-NVG599-WI RELESS-AC-AC1600) in my area. Once I get my hands on it will report back on how it will react to all the steps above and hopefully work well with Time Capsule.
Shoot me any questions you might have. Hope this was helpful for some of you.

Problems with XB3 gateway; it won't connect to internet properly in bridge mode

I recently moved to a new area and had to replace my old gateway from the other comcast franchise with a new one. The new one has built-in wifi. Ever since I got the new gateway, my connection has been slow and unreliable, especially when more than one person is trying to use a computer at once, and I do not like that this wifi is interfering with the setup I was previously happy with using my airport time capsule as a router, with my old airport express in bridge mode for airtunes use. In that setup with the same people and devices and use habits I did not have these problems. I looked for directions on how to disable the built-in wifi (I also don't like just putting out connections I do not use, it feels like a waste of my signal and a security risk!) and followed the instructions i found on this forum which seemed very simple. I logged in to the gateway and turned bridge mode on, restarted everything, switched the time capsule back OUT of bridge mode... and my time capsule and airport were all green, as well as the online login to the gateway saying it was connected to the internet, but my time capsule showed that there was no internet connection and in terms of loading web pages... deifnitely the time capsule was correct in that I was not getting a connection. My computers and devices weren't showing up on the gateway's page as "connected devices" either. I've tried multiple times, reset everything multiple times, and rechecked directions but for now I had to re-enable the wifi and suddenly i can get online again. (And no, it's not that my computer is actually using those netowrks - I'm on my Time Capsule's network and checking the status through the airport utility.) I really want to get this extra wifi disabled and see if that resolves my crappy connection problems because the service is just useless in the evening as it is now! If anyone knows what might be wrong, I'd appreciate the help. Everything should be on pretty standard settings as far as my Time Capsule and Airport go - Airport is just in client mode, TC has to be in bridge mode when the other wifi is on or I get errors, but i haven't done anything fancy with any of its settings.

Hi, since you have 2 Linksys devices and it's hard to pinpoint the exact problem. You might the try doing changes on both Linksys devices.
WRT54GX2
- update or reflash the firmware
- change the channel from auto to 11 or 1
- change the beacon interval value to 50

- download and update to the latest drivers

ACE dropped conns problem (Bridged mode)

Dear all,
I configured an ACE in bridged mode (inside vlan: 2012, outside vlan: 2021) and I apply the L4 policy on the 2 VLAN interface to loadbalance HTTP incoming request (Virtual IP: 172.22.22.130).
interface vlan 2112
bridge-group 1
access-group input BPDU-Allow
service-policy input POLICY-LB-HMC-2112
no shutdown
interface vlan 2122
bridge-group 1
access-group input BPDU-Allow
service-policy input POLICY-LB-HMC-2112
no shutdown
But I need also that some other server connected to the same vlan 2112 and having to send HTTP request on the same VIP but this failed and I get dropped conns.
Can anyone helps?
Regards
Abdelaziz

Hi Olivier,
This below the full config, and my need is to make a server in the inside VLAN 2112 (172.22.22.121) to open HTTPS connexion on the VIP (172.22.22.130 for rserver .131 & .132). Trafic from the outside is working well.
Thanx,

Since cahnging FIOS Internet provider, which required a router to go in front of "AirPort" I have a blinking yellow on the AirPort and suggested editing in AirPort utility to cahnge from Double NAT to "Bridge Mode" my knowledge base is not clear as t

How do I clean up my new FIOS connection? I just cahnged ISP Fios and they reqquired a router of thier own in front of my AirPort Extreme. Since then I have blinking yellow light on the AirPort and AirPort utility keeps promting for an edit. Suggests canging from NAT to "Bridge mode". Obviuosly U have some internet or this post would not go anywhere, my knowledge base is not enought to feel comfortable with changing the settings. Correctly editing can be tricky, so how do I make necessary changes?

How do I clean up my new FIOS connection?
The FIOS router needs to be in Bridge Mode to prevent the Double NAT error from occurring when two routers are both fighting with each other for control of the network.
Unfortunately, the likely problem from the FIOS side is that FIOS support will either tell you that their router cannot be configured to operate in Bridge Mode, or if it can, they will not tell you how to do it.
But, it could not hurt to check with FIOS to see if anything might have changed recently in this regard, so your first call would be to FIOS support.
If you cannot change the FIOS router to Bridge Mode, the alternate plan would be to change the AirPort Extreme to Bridge Mode. If you are using the Guest Network feature on the AirPort Extreme at this time, that feature will not work correctly when the AirPort is set up in Bridge Mode.

New Airport Extreme in Bridge mode -- some devices have no internet access

I just bought a new Airport Extreme as my old one which was probably 7 years old required restarting every day. My setup is as follows: DSL cable modem to Linksys Router (for a long set of convoluted reasons, I can't remove this layer) and then Airport Extreme. This is how I had it set up with my old one. The only difference is I recently started looking into using "Back to the Mac" on MobileMe and in order for it to work, I set my new Airport Extreme to Bridge mode due to dual NAT. I have an iMac, PC, MBP, MBA, iphone 4, AppleTV and ipad. All was working fine last night when I set it up. 24 hours later, for some odd reasons, I can't have my PC accessing the wireless network at the same time. If I did, it would knock my iMac off the network and says some other device is using the same IP address. For a while, only my iMac (my main computer) can access it and even my iphone can't. At this very moment, my iphone, imac and MBP all have access to the wireless network. My MBA and iPad has no internet connection. I've restarted Airport Extreme, Linksys, and modem more than once... If I switch back to "Use Public IP Address" instead of Bridge mode, everything works except for "Back to the Mac"... Help!

Hey Bob, Thanks...I have already repeated that multiple times yesterday and today but to no avail. I tried to get into the Linksys router control panel but unfortunately we can't remember the username and password (the router is not mine). The make things even more complicated, the router is actually part of the internet package provided by the ISP and they use a PPPoE to log in. Theoretically, we could do a hard reset but the problem is the ISP will not release the PPPoE information unless we sign a long and complicated form saying we want to bypass their Linksys router. We can do that but this process will take days and weeks... Our ISP confirmed that the Linksys router is set to max out at 5 DHCP but we can only connect 3 machines at a time. They are coming out to take a look tomorrow but in the meantime I have reset the Airport Extreme to "Distribute a Public IP Address" mode which will allow access to all computers/devices. What's even more weird is that if I did the Bridge mode, it messes up the Linksys router's own network as well. We can't even just sign into that network... Any ideas why?

Why do I lose internet connection when I put airport extreme into bridge mode to correct Double NAT issue

I reset my airport extreme router the other day because I was too lazy to reset the password on my private network.
I have been reading the advice found on apple support communities and wide web, but the solutions do not solve any problems and often create new ones.
I'm regretting because everything was working just fine.
But I remember having this double nat error when I first set it up a few months back, but now I cannot resolve it.
I would live with the yellow light, but it seems that this double nat error is preventing my playstation 3 from connecting to the airport extreme.
When I put the aiport extreme into bridge mode, I loose all my wireless networks, even when I reboot the airport extreme and the modem.
I try rebooting the modem, then the airport. and vice versa. No internet.
I switch back to NAT/DCHP and the internet works fine on apple devices, but not the playstation 3, and I have the 1 Double NAT error.
I have a plain stock Motorolla modem and I can dial in and see settings (although nothing about NAT). I didn't see where to see them.
I tried setting the DHCP only but it said it didn't like the settings. is there a stock range i could be using?

I have a plain stock Motorolla modem and I can dial in and see settings (although nothing about NAT). I didn't see where to see them.
Exact model .. motorola make adsl, cable and probably wireless modems.. with some modems and some modem router.. we need exact info. What kind of broadband do you have?
I would note.. some of the motorola cable modems seem to have issues with the apple routers. If you are about due to change modems.. now is a good time.. not another motorola.
If the modem is a straight cable modem, the AE must be in router mode.. but you need to power down the cable modem. maybe for 20min so the new router can pick up the IP address.
You cannot use DHCP alone.. the ISP do not give you a block of IP addresses.
You cannot use bridge with a pure modem.. you will find it works.. but only to one device.
The only reason you get double NAT is the failure to pick up the public IP.
Give the info required..
If you have trouble, I need the actual IP of the modem. the actual IP of the AE WAN port when plugged in. Screenshots are good.

Is it possible for SA540 to work in transparent bridge mode?

Hi all,
I've been considering to use a Cisco SA540 in an industrial project; please consider Scenario 1 and 2 files attached (bear with me - I'm an engineer, not an artist).
All networks mentioned in both scenarios are regular and well known Ethernet TCP/IP networks. The Corporate Network and Automation Network (including the DMZ) are in different subnets. The Corporate Network is the biggest one, similar to any company's corporate network you all know. The Automation Network exists for the purpose of operating and maintaining the industry process; it's smaller but highly critical. Only specific staff (automation staff and dedicated operators) have access to it. Although many devices and networks in the Automation Network are industry specific - not so well known, a small segment of it is plain Ethernet TCP/IP, as I've already stated. The Automation Network has a DMZ, where we lay servers that provide industry process information for the Corporate Network.
Scenario 2 may look at a first glance the best option, since it's simpler, doesn't require another router and benefits from Cisco SA540 support for both a LAN and a DMZ. The problem with Scenario 2 is the following:
Since both networks are maintained by different teams under different management, TI staff would have absolute control over the Cisco SA540. This way automation staff could not grant that the Automation Network is really protected from the Corporate Network.
TI staff may even demand for another device to interface with the Automation Network - which is not Cisco SA540, since they rule everything that lives in the Corporate Network. In this case, I have my hands tied!
Scenario 1 solves the above problems. Since automation would have absolute control over the Cisco SA540, they could grant security for the Automation Network (except for DMZ, but that's the reason why it is called a DMZ!). TI staff could ask for any router they prefer to interface with the DMZ, I would never mind about it.
Considering the above, I will probably be forced to adopt Scenario 1 instead of Scenario 2. So here comes my question: is it possible for Cisco SA540 to work with the same subnet for both WAN and LAN interfaces (in Scenario 1, no DMZ interface is required)? In other words, is it possible for Cisco SA540 to work in transparent bridge mode? I've been through all of the Cisco SA540 Administration Manual and as far as I could understand, routing is not an option - it is demanding.
Although I understand I could adopt Scenario 1 and still have different subnets for DMZ and the rest of the Automation Network by connecting the DMZ to the WAN interface and the rest of the Automation Network to the LAN interface in the Cisco SA540, I believe it's not worth the effort. The Automation Network is so small and we do all we can to keep it as simple as possible.

Adriano, there is a RV042G, which supports the gig ports and a 800 mbps nat throughput. Here is the datasheet
http://www.cisco.com/en/US/prod/collateral/routers/ps10907/ps9923/ps12262/data_sheet_c78-706724.html
If you are using a DSL connection, the SRP527/547 models may be an alternative. These models support the RFC 1483 Bridges EOA Please note the SRP547 should be 10/100/1000. Also note the SRP521/541 are Fast Ethernet units and they do differ from the SRP527/547. The main selling point of these devices are the FXS/FXO ports. So this may also be a bit of an "unfocused" solution. But it's worth throwing the idea out there!

Guest network in bridged mode (or other non-DHCP mode)

Hello,
I have the (Simultaneous Dual Band II) Airport extreme.
I wanted to use it at work but creating a secure network (my printer, computers, and drives) and a guest network (no password so people can access internet).
They already have a DHCP server (in the past I have a mistake by forgetting to turn off DHCP on a router which assigned other computers IP address (upstream) which conflicted with their DHCP server and all kinds of problems ensued).
So I know that in Bridge Mode, the guest network is turned off.
What are my options? I'm afraid to take if off bridge mode because of the DHCP issue. But I really want to use the dual network mode on the Airport Extreme.
So I don't want to bring down the whole network, can i safely use something other than bridge mode? other ideas?
Thanks in advance for any feedback
(yes I have searched a lot for the issue but I'm not sure what to do)

First, you question the policies about my work place (none of your business).
Sorry for suggesting that you check the policies before you violate something that could get you fired.
But then, you "would bet" that I hooked something wrong (could have asked).
Sorry but that is certainly a higher probability than a router malfunctioning in that manner.
It may not be your intention (just as it is not mine to be ungrateful).
Not sure if you are showing that with your last post.
