Http secure-server on 887VA in bridge mode

I'm setting up an 887VA to bridge between vlan1 and the atm0 interface. For remote management and to access the https for web management on this device, can I pop one of the 4 fe interfaces into a different vlan to assign it an IP address?
Not critical, but since you can't assign individual fe interfaces to the bridge group, it would be nice.

HI Gilles,
this is quite confusing as I learnt in a workshop with some Cisco SEs that the CSM is bridging all traffic which is not destined to a VIP if you do bridged mode. I agree with you that you realy need the predictor if you are running secure/routed mode.
However Chi Wang (I hope that's your forename):
In regards of your first question:
I think nothing has to be done to get the reals directly the only thing which has to be ensured it that they are plugged in the correct vlan and reside in that vlan.
In regards of your second question:
Have you checked if the routing from the servers to the GW is done correctly (towards a gateway in the Layer3 subnett?)
Btw are the servers connected in the server vlan?
Have you done a ping from the MSFC towards the servers?
have you done a traceroute from the servers to the destination you want to reach? Where does the traceroute stop?
Some additional questions from my side:
You set up the CSM in bridged-mode however the reals could be on a different LAyer3 hop? What's your topologiy maybe you can give us a hint of how you config looks like and what's the topology.
Kind Regards,
Joerg

Difference between bridge mode and routed mode on CSS

Hi,
Could some one tell me the difference between routed mode and bridge mode.
Regards
Neha

Hi,
routed mode:
The CSS acts as a router, it routes packets from the client to the server. The server has the ACE configured as default-gateway.
There is a client-side VLAN and a server-side VLAN. These VLANs have different subnets.
Bridged mode:
The CSS acts as a bridge, it switches frames from the client to the server. The server has the upstream router configured as default-gateway.
There is a client-side VLAN and a server-side VLAN. These VLANs have the same subnet, but different VLAN IDs. The ACE bridges the client traffic from the client-side VLAN to the server-side VLAN.
Bridged mode would be most used in case one cannot change the servers IP addresses, or if address space is an issue.
Hope this helps.
Kind regards,
Dario

ACE30-MOD-k9 in bridge mode. Individual server in the same vlan of Real Servers not reacheable.

I configured ACE30-MOD-K9 in bridge mode and I configured a server farm with his real servers. The traffic passes and is balanced correctly between all RSERVER. But I can not contact a server that is on the same vlan of the serverpharm but doesn't belong at this serverfarm.
I Thought that the traffic directed to this "spare" server shouldn't be balanced but the bridge should permit traffic to pass. (trasperent mode) Is it correct ?
What does ACE in bridge mode with traffic directed to servers that do not belong to any server farm but are present on the same VLAN (same bridge group)?

Hi Francesco,
Just to add more a bit, A bridge group is very similar to routed mode except ACE cannot NAT pass through traffic, vlan's cannot be shared and couple of other things but client's should be able to access the server as in before.
But also whether in bridge or routed mode, ACE does create flows and applies other security parameters if configured to the traffic. This is for security. Also, ACE should know the MAC of the device to forward the traffic to. Can you check if ACE has the MAC of the destination? You can also put a route for testing purpose and see if that resolves the issue. That should probably be the quickest way to check if ACE is creating any issue here.

Arris modem & AEBS in bridge mode w/ OS X server (Yosemite)

I have been using a AEBS (ac) as router in bridge mode behind an Arris cable modem (with its own wireless network setup) and have it create a wireless network. I extended it with 1xAEBS (ac) and 2x AEBS (n) to reach all corners of the house, all in "extend" and "bridge" mode. The AEBS (ac) router is using Ethernet cable to connect to Arris modem. This setup worked well for me and still does, until...
Recently, to get access to my files on the network from the Internet, I installed OS X server (4.2) on Yosemite running on a MP (have a few drives attached). I intend to use the servers VPN service, but cannot get its new reachability tool to identify any services running. After doing some searching I found tutorials on how to run the AEBS in DHCP and NAT mode, which results in a double NAT error the way my modem/provider service is setup.
I have not been able to find a tutorial how to configure the server in Internet mode behind the AEBS (ac) router in bridge mode. I do have a domain name, but the service provider does not offer Dynamic DNS service. And I did let the server install the DNS services automatically.
A server setup guide when running AEBS in bridge mode would be very helpful.
I would need some help configuring the AEBS router as well as setting up the server - thanks a lot!

I see nobody else has jumped in.. so I read this last night and thought it was a bit too hard..
But perhaps I can get you to at least clarify some stuff.
Arris cable modem (with its own wireless network setup)
What model is the arris? Since it has its own wireless it is a router.. or what is sometimes called gateway.
I have been using a AEBS (ac) as router in bridge mode
You cannot use "as router" in bridge.. they are opposites.. but I think you just mean.. AEBS is in bridge.. the mention of router is to qualify the AEBS which we know is a router.
I intend to use the servers VPN service, but cannot get its new reachability tool to identify any services running.
I do not use server and I would not have done the setup this way to get access to your files.. but the vpn service should work.
Test by using a computer on the local network running a vpn client to see if you can log in to the server. It is much easier to get things working locally before you attempt to do it remotely.
What type of vpn is it.. I can look it up but easier if you post the details.. each vpn uses different port forwarding requirements. PPTP is different to IPSEC which is different to L2TP which is different to SSL.
After doing some searching I found tutorials on how to run the AEBS in DHCP and NAT mode, which results in a double NAT error the way my modem/provider service is setup.
You cannot run two routers.. that will mess things up. The AEBS should be in bridge.. double NAT will kill your access.
I have not been able to find a tutorial how to configure the server in Internet mode behind the AEBS (ac) router in bridge mode. I do have a domain name, but the service provider does not offer Dynamic DNS service. And I did let the server install the DNS services automatically.
Some of this I have not used.. so I cannot say much.. I much prefer to do vpn using vpn routers.. it is far easier.
Anyway.. the bridged AEBS is irrelevant.. your problem is needing to setup the Arris for VPN pass through. This sometimes involves something simple like tick a box.. it can also be complicated and need port forwarding.
You can use Dynamic DNS client in the Arris.. that will be the best place to set this up.
You will need to download and read carefully the manual for your arris gateway.
Let me also suggest you run ethernet directly to the arris .. bypass the Extreme altogether.. it is not related to this setup but can cause issues.. because Apple have some inbuilt ipsec security for BTMM.
For setting up yosemite server to do vpn I recommend you post in the Server OS area of the discussions.

Question about TC setup, bridge mode and security...

Hello All
I need some help...
Have bought a 1 Tb TC to use with my existing ethernet/wireless all-Mac home network but have some specific queries.
The system is set-up as follows:
Cable modem > connected by ethernet cable to > 8-way Ethernet switch
Connected via ethernet cable to the 8-way switch are: one MacBook (in another part of the house) and the TC (via its WAN socket).
Elsewhere in the house, and _all connected wirelessly_ are:
iMac G5
Powerbook G4
hi-fi (connected via an Airport Express)
Airport Extreme basestation to which a HP Laserjet is connected via ethernet.
Question:
Before buying the TC, I used a spare Airport Express basestation in its place to act as the 'main' basestation and the IP addresses of each device on the network were 10.0.0.1, 2, 3, etc. I had the impression that my home network was not "seen" by the outside world as a consequence of this.
Now, the TC seems only to work when in 'bridge' mode and it seems that the IP addresses are 196.xxx.x.100, 101, 102 etc. Does this mean that these devices are now visible to the outside world. Have I compromised my network security? I am worried that the outside world may have access to the contents of my TC, although my TC is password protected and the wireless network is 'closed'. What else should I be doing?
Finally, should I have set up the network so that the cable modem feeds to TC directly, with the 8-way ethernet switch coming off one of the ethernet sockets on the TC?
In all honestly, the instructions in the manual and the help guide are less than clear.
Can anyone help?
Thanks
Daniel

Section 4, here are my thoughts.
1. Since you are currently seeing individual IP addresses like 196.xxx.xxx.100, etc., it sounds like your modem is also acting as a router. This also seems to be the case since the Time Capsule is only working in bridged mode (it wouldn't work in Share a Public IP address if another device is assigning private DHCP addresses). Now, you could still allow the Time Capsule to act as a DHCP server on your private network by enabling Connection Sharing as Distribute a range of IP addresses. This will create a private network within your private network where all the devices that are connected to your Time Capsule can see each other. If you leave it in bridged mode then you allow your cable modem to assign DHCP addresses and all devices that are connected to the Time Capsule or to your ethernet switch are on the same network.
2. Assuming your cable modem is acting as a router you shouldn't have to worry about security, although you will have to access your modem's settings to make sure port forwarding isn't enabled and that the firewall is turned on (although I'm sure it is). I personally would plug the ethernet switch into the LAN port of the Time Capsule and allow the WAN port of the Time Capsule to be plugged into the cable modem. I also would just leave the Time Capsule in bridged mode as well, that's what I do for my own personal network.

WAN security in bridge mode

Greetings!
I have an Airport Extreme 802.11n hooked up to a cable modem, and I am pondering switching the Airport from NAT mode to bridge mode. The purpose is to give each client on the network its own WAN IP. As I share an apartment with two friends, this has benefits in that it allows each of us to be as hidden or visible on the internet as we like, without disadvantage to the others.
I am looking for some input on the security implications of this besides the obvious fact that all clients are now solely dependent on their own firewalls.
Some questions:
- I have two hard drives shared with AirDisk. If I have deselected the option to make them available via WAN, is this enough to keep anyone from accessing them from the outside?
- I know there is a lot of "background noise" on the internet – random infested computers scanning random IPs. This will of course be stopped by the firewalls on the clients (of which two of three are Macs), but is this traffic of such a volume that wireless performance will be affected?
- Do you have any other thoughts on the implications of such a configuration?
Any input is greatly appreciated!

Your ISP is most likely only allowing you one IP number. While you might be able to call them up and have another number added to your connection, if this is available, it will cost you more money. NAT not only acts as a firewall but it splits the one IP number up between two computers so that you don't have to pay an ISP for every piece of hardware on your network.
Even if you have share over WAN disabled, when you turn on bridge mode, that setting will disappear is it no longer applies and it will be accessible over the network.
So what do we have now? Your computer will be requesting an IP number and your roommates computer will be requesting one too, but wait the AEBS also wants its own number, so that's three numbers, plus you will also not be able to block people from trying to change settings on your router.
If you or your roommate are running any software that requires it be recognized by incoming network traffic, then take a look into setting up port forwarding or turning on host computer for for whichever machine needs this.

Adding direct server access to CSM in bridge mode

I have a CSM that I have set up in bridge mode and want to allow direct management access to the real servers.
It looks like this. MSFC 10.1.100.1
CSM 10.1.100.3
Reals 10.1.100.10
10.1.100.20
10.1.100.25
Virtual 10.1.100.130
10.1.100.140
I tried to use the same method that I found for routed mode on CCO.
Serverfarm SERVER-SUBNET
No nat server
Predictor forward
Vserver DIRECT-ACCESS
Virtual 10.1.100.0 255.255.255.0 tcp any
Serverfarm SERVER-SUBNET
Inservice
The next step in the documentation says to add a static route to the CSM
Ip route 10.1.100.0 255.255.255.0 10.1.100.3
But this does not make since since the MSFC 10.1.100.1 address is already the default gateway.
So is there another way to configure bridge mode and enable direct management access?

After I thought about bridge mode again and took out the direct-access and server-subnet commands. I tested again and I can now directly access the servers.

After Installing Oracle Virtual Box and changing the network adapter to bridged mode cant access my server

Hi ,
I have installed Oracle Virtual box on windows server 2008 r2 hosted on 1und1.de.
Till installtion and setting up untun on virtualbox it was fine, but once i changed the adapater to bridged mode. I immediatly lost connectivity with my server and now cant access.
It is now 2 days i cant access my server and neither ping it, also the website hosted on it is also down.
The 1und1 has following 2 options
1) using putty i can connect to server command prompt using administrator but cant run any gui application
2) Server Rescue mode: where i get special environment to start, stop services, access registry and command prompt.
Till now i have tried lot of setting to enable network connectivity but not able to success
This is the result of Ipconfig /all

Hi,
According to the result of "ipconfig /all", the physical adapter dosen't appear.
Please check if the physical network adapter works properly. We can verify this in Device Manager.
To open Device Manager by using the Windows interface
Click Start, and then click Control Panel.
Click Hardware and Sound.
Click Device Manager.
If the network adapter is working properly, please make sure that the Internet Protocol Version 4(TCP/IPv4) has been checked in the properties of the physical network adapter.
If issue persists, please try to uninstall the Oracle Virtual box.
Best Regards.

Does putting the airport in bridge mode effect the security of the internal private network

If I put my Airport Extreme in bridge mode for running Echolink, will it effect the security of my internal private network?

Not at all.

CSM in Bridge mode and Server initiated connections

I know one can use Source NAT for server initiated connections back to VIP using CSM in routed mode. How do I achieve the same for bridge mode?
Thanks in advance,
Shahid

Shahid,
that's a well-known problem for all loadbalancer in the world.
With a sniffer trace, or just thinking about TCP/IP rules you can figure out why client nat is required.
If you go from a server to a vip, the CSM will forward the traffic to a random server.
The CSM forwards the traffic with the source ip unchanged by default.
The server receiving the traffic will forward the response back to the source that initiated the request.
If the source is also a server in the same subnet, the response does not need to be sent through a gateway. Since both source and destination are in the same subnet, the traffic is sent based on mac address and it bypasses the CSM which can't perform the nating.
The source receiving the response from the server directly will just ignore it.
Using client nat forces the response to go back to the CSM which can perform the nating before sending it to the client.
This has been discussed tons of times in this forum.
It's a classic question :-)
Gilles.

Is bridge mode secure?

I am using a imac connected to Time Capsule, then to tmobile cell spot booster, then to comcast modem. Apparently each has a function. But the TC made me change its setting to Bridge Mode. I'd wondering if this is less secure. Does the security come through the sign in I have to do for the Comcast and TMobile routers?

The security is furnished by the main network router, so in your case bridge mode is secure since you are connecting to the main network router.

Deploying CSM in Bridge Mode into an existing server envronment

We have installed two CSM's in a 6509's in a network that has servers already in an existing subnet and vlan.My question is.Can I use the same vlan that the servers are on at this time for the server slb vlan or do I have to create another server slb vlan in the subnet?

the servers can stay in the same vlan.
But if you want bridge mode, you will need to configure 2 vlans in the CSM using the same subnet.
1 vlan will be the same as the servers.
The 2nd vlan will be a new vlan using the same ip subnet.
The MSFC should be setup with only the 2nd vlan.
So at the end you get
MSFC---VLAN-A----CSM-----VLAN-B----SERVERS
<-------------- one subnet --------------->
The servers can keep the same gateway ip address.
This ip address should be moved from current msfc vlan to the newly created vlan.
[I say MSFC, but it could be any other router being currently the default gateway]

Security Cameras & Bridge Mode

Hello,
I am instaling wireless security cameras in my house and I want to be able to monitor things while I am out of town. Try as I might, I am unable to see the cameras outside of my network. When I try to see the port at my current IP, I will get messages similar to "Connection Timeout"
I have a G90-610015-20 DSL modem using PPP0E Protocol. Would switching the modem to bridge mode help?

Yes that would help, as long as: #1 You have a RJ-45 WAN port router. #2 The RJ-45 WAN port of it is connected to the modem combo. #3 And you know the PPPoE Log-in info (user name and password)

Share Airport Connection to Ethernet port in BRIDGE mode?

I've been trying to do this for a while now, but I haven't been able.
I have the modem form my ISP hooked to a Airport Express configured in BRIDGE mode, thus creating a wireless network for my home with "live" IPs for all the computers (yes... I know the security risks...).
My G4 (across the room) gets Internet from it's Airport Card and I configured the Share Internet preference pane to "Share the Internet Connection from the Airport to the Ethernet Port", so I can create (...extend, really) a WIRED network from my G4's Ethernet Port.
The thing is that I want this wired network to have also "live" IPs, but the Airport Card always has the "Distribute IP Addresses" (or it's equivalent, from the Airport Admin Setup) activated, so it provides a 192.168.X.X network and I can't find a way to turn that off.
In other words, I want it to acts as a BRIDGE and not as DHCP Server.
Anyone?
TIA

I was trying to use IPNetShareX to configure it, but I didn't find a way. I'll keep looking...
