ASA supports NAT in bridge mode??

any one know if an ASA supports NAT in bridge mode? especially the 5580 series x??

Hi Hans,
Yes it does, from version 8.0 and higher.
Unsupported Features
These features are not supported in transparent mode:
NAT /PAT
NAT is performed on the upstream router.
Note: Starting with ASA/PIX 8.0(2), NAT/PAT is supported in the transparent firewall.

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.

How to change Cisco EPC2425 into bridge mode

Hi,
I need help regarding how to chage ECP2425 into bridge mode. I have Wireless NAS drive router which has its own DHCP and NAT service. At the moment my Wireless Timecapsule (NAS Drive) is in bridge mode and connected to EPC2425 with ethernet cable. Everything is fine. But in order to access my timecapsule over the internet, I need to use its (timecapsule)'s NAT service. For this, I need to put EPC2425 which is my first point of access from internet, into bridge mode or atleast disabled its (EPC2425) NAT service. Unfortunately, I am not been able to find NAT or Bridge mode option on EPC2425. I will appreciate if anyone can help me out in this case. I need to change my EPC2425 router into bridge mode or gateway mode.
Thank you very much

Hi Azhar,
Thank you for your question. However, this community is for Cisco Small Business Products and the DPC/EPC2425 is not a Cisco Small Business Product.
Your product is an internet service provider (ISP) supported product. In other words you need to contact your ISP or technology reseller that you purchased this from to help you with your question.

Does ACE-30 support multicast in routed mode?

We currently have ACE20's, which only support multicast in bridge mode.
Was wondering if it's the same on ACE30's, or if Cisco finally implemented support for mcast in routed mode.
thx
Kevin

Could you please confirm if this applies to both ACE20 & ACE30, or just ACE20?
If both, when does Cisco plan on supporting mcast in routed mode?
thx
Kevin

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.

Ace module in bridged mode with client nat

Could someone confirm whatever a NAT is supported for ACE-20 module, please?
Let me to explain technical details.
I do need to convert working CSM(SLB) config to ACE configuration and I am not quite sure
if the configuration below is correct. ACE module should be configured in bridge mode with two
vlans - vlan 36 (client) and vlan 436 (server) - bridged with interface bvi 36.
NAT on ACE configurad as "nat dynamic 1025 vlan 436" into corresponding
"policy-map type loadbalance"
Could you check two parts of configs and advise me if the ACE config is
properly converted from CSM and will be working in the same way (especialy for NAT).
Thank you in advance.

Hello F.Makarenko-
You will want to use PAT while you do nat, so change the natpool configuration to this:
   nat-pool 1025 10.36.3.100 10.36.3.100 netmask 255.255.255.0 pat
You also need to apply the nat like this:
policy-map multi-match IFVLAN36-POLICY
class WEBMAIL-80
    appl-parameter http advanced-options HTTP_ADV_OPT
    loadbalance policy WEBMAIL-80
    loadbalance vip inservice
    loadbalance vip icmp-reply active
    nat dynamic 1025 vlan 436
class WEBMAIL-443
    appl-parameter http advanced-options HTTP_ADV_OPT
    loadbalance policy WEBMAIL-443
    loadbalance vip inservice
    loadbalance vip icmp-reply active
    nat dynamic 1025 vlan 436
If you are going to build out a lot of classes, you can instead do source nat like this:
policy-map multi-match IFVLAN36-POLICY
class WEBMAIL-80
    appl-parameter http advanced-options HTTP_ADV_OPT
    loadbalance policy WEBMAIL-80
    loadbalance vip inservice
    loadbalance vip icmp-reply active
class WEBMAIL-443
    appl-parameter http advanced-options HTTP_ADV_OPT
    loadbalance policy WEBMAIL-443
    loadbalance vip inservice
    loadbalance vip icmp-reply active
class class-default
    nat dynamic 1025 vlan 436

I have a new comcast modem i have connected to Time Capsule with cable, TC in double NAT. As when I tried it in bridge mode I cannot use Sonos, the units will not connect to the wifi network? I thought Bridge mode would make the wifi signal better??

I have the TC connected to the comcast modem, with TC in Double NAT mode. I set up the sonos music players ok. But I read that to incresae the wifi signal the TC should be in Bridge mode. Then I cannot get any of the Sonos units to connect to the wifi network.
So two questions, does the Bridge mode give a better wifi signal then double NAT?
Why will sonos not connect to the network when in Bridge mode?

A PC can have more issues connecting than a Mac.
But it really should not matter.. so just try it in situ.. press and hold the reset.. once it starts up, it will return to default IP, 10.0.1.1 the PC should then be able to find it via the airport utility.
If not drag it over to the Mac and plug in there by ethernet.. or since it is a laptop, really should not be that difficult to drag the Laptop and plug it into the TC.
Important thing is to get access to the TC.
The Mac if it is running lion, then you MUST download and install 5.6 airport utility to do anything useful.

I am attempting to set up a guest network on the Airport Extreme Base Station. The Base Station is connected to a DSL Modem. The network is also extended using an Airport Express. When I have attempted to set up the Base Station using DHCP NAT in the netword feature I get a message that because the service has a private IP address the only way that I can connect is in Off Bridge Mode. In this mode I do not seem to be able to connect to the internet using the guest network. Any suggestions would be helpful.

Ok, your Speedport is actually a combination DSL modem and wireless router. In this case you would typically configure a downstream router, like your AirPort Extreme in Bridge mode. Unfortunately, when in Bridge mode, the AirPort does NOT support providing a guest network.
The only possible option is to reconfigure the Speedport as a bridge and use the Extreme as your Internet router. You would still need the DSL modem provided by the Speedport for Internet connectivity.

X3500 wont work in Bridge mode with ASA 5505

Hi Everyone, I am currently running Linksys X3500 v1.0.0 and plan to use ASA 5505 as a PPPoE client. While PPPoE connection is working fine when i configure the linksys for PPoE, but When I configure the ASA 5505 to act as PPPoE client I'm unable to get the Linksys get the Internet up and running. I have opened support ticket with Cisco and per them X3500 is unable to provide PPPoE details in bridge mode. Cisco Ticket # 62968611 (PPPoE connection not working) The error on Cisco console is - asa5505# PPPoE: send_padiSnd) Dest:ffff.ffff.ffff Src:c8b3.735d.4e13 Type:0x8863=PPPoE-Discovery PPPoE: Ver:1 Type:1 Code:09=PADI Sess:0 Len:12 PPPoE: Type:0101VCNAME-Service Name Len:0 PPPoE: Type:0103:HOSTUNIQ-Host Unique Tag Len:4 PPPoE: 00000002 PPPoE: padi timer expired Can Linksys help.. What's the issue. Regards, Sumit

Hi! I'm not so familiar with the Cisco ASA 5505 device. If you set your X3500 to a Bridge Mode, it will not give any PPPoE mode details and vice versa. Which of the two devices would you like to connect to the ISP's connection, is it the X3500 or the ASA 5505?

Can a single Access Point support both bridge mode and Access Point mode at the same time

Hi Guys
Does anyone know which access point can work in both bridge mode and AP mode ?
Cheers

Well what are you trying to cover. If its really a large outdoor area, then look at the mesh AP. Those require a WLC. Autonomous or stand alone ap can perform bridging on one radio and client access on another. You can also look at AP that support indoor mesh that also controlled by a wlc. If your putting APs outdoors, then look at the outdoor mesh.

I live in an apartment with supplied internet. I have wireless network with no password. I have a wall outlet that I can plug into. When I plug in my TC I get a double NAT error. I try bridge mode, but I can't get the internet to work.

Can I get an explanation of what bridge mode is?
Can I get suggestions on what I should do to use the TC as a wireless device to spread the same wireless device my apartment is broadcasting?
Can I get a suggestion on how to use the TC as a different wireless device with it's own password without access to the cable modem. I only have access to a wall port.
I own many apple devices, iMac mid-2011, Macbook Air 2013, 2 ipads, and 2 iphones for the family, and Apple TV.
I want all my devices to be on a password related internet but the double nat on my TC makes weird things happen and slow. I try bridge mode but the internet doesn't work.
I hope I have described this situation clearly enough.
Thanks

I want all my devices to be on a password related internet but the double nat on my TC makes weird things happen and slow. I try bridge mode but the internet doesn't work.
You building supplied internet is a cheap service that is without proper routable addresses..
Therefore to use more than one IP you MUST have double NAT.. sorry there is no choice..
Slow that is because you are sharing internet with every other person in the building.. get your own broadband service.
Bridge will not work.. it cannot work because the building only has private IP addressing. And they only give you a single address.
You can put a password on the wireless.. go to the airport utility and put in a password.
Other than that I don't understand what password you expect.
Can I get an explanation of what bridge mode is?
No NAT.. means the TC becomes a dumb Wireless AP and switch.. works fine with a cable modem router.. or any broadband router but useless with your building system.
Can I get suggestions on what I should do to use the TC as a wireless device to spread the same wireless device my apartment is broadcasting?
Double NAT, and set your own wireless names. There is no alternative.. sorry.

Bridge mode not supported for lap1261N

Hello,
I have a WLC2504 and 2 LAP1261N (converted from autonomous to lightweight) with release 7.0.116.0 and I want to create a point-to-point mesh link between the 2 APs. When trying to change the APs mode from local to bridge I receive the message "This AP does not support bridge mode" even if the release notes say that mesh is supported on AP1261N. I tried to change the mode from gui and also from CLI. Any suggestion?
Thanks,
Paolo

in aIOS you can tell it to bridge on the 2.4GHz Radio, it's not ideal but it can be done.
for WLC based:
The Cisco 1130 and 1240 ( all indoor AP ) are equipped with the following two simultaneously operating radios:
•2.4-GHz radio used for client access
•5-GHz radio used for data backhaul
The 5-GHz radio supports the 5.15 GHz, 5.25 GHz, 5.47, and 5.8 GHz bands.

Airport in Bridge mode "not a supported format." Are you F'n kidding me?

Forgive me if I'm freakin' a bit but I am at my wits end with Apple. Here's the breakdown.
Fiber DSL into a standard wired 4 port D-Link router. Router is connected to HP 24 port switch because the D-Link does not have enough ports for my house. Switch feeds cat5 to all rooms in the house. Airport Extreme (newest version) is in living room and set to Bridge mode. I use it to connect multiple items in my entertainment area and wireless access for the Macbooks and iPhones.
Up to a few weeks ago I was connecting my iMac via wireless but got sick of the connection dropping (pings would be unresponsive for minutes on end). I ended up moving my desk and plugging into a cat5 port on the wall. Well guess what... it's still dropping. OK, I removed everything from the network and started adding things one at a time over the past few days. Everything was running better than ever until I plugged the Airport back into the network. Mind you, I'm not running my iMac into the Airport, it is simply on the same network.
After shaking my head for a while I called Apple. Well I just got off the phone w/ Tier 3 tech support for the Airport Extremes. I tell them that I have no idea why, but I'm only dropping connections when the Airport is on the network and I'm just curious if there is something in the settings that I'm missing. This is where it gets good... The brilliant Tier 3 "Technician" tells me that I am running an unsupported configuration because the Airport is running in bridge mode and it's attached to a wired router across the house. He says that if the D-Link router was also wireless he could help me. I asked what the difference was if it was wired or wireless but all he could say was he couldn't help me because it was a unsupported configuration.
So - I'm ready to send all my CrApple gear to some poor kids on the other side of the world. Anyone have any ideas here?

I'm reading the original post with the understanding that the AirPort Extreme is connected by ethernet to the network and the replies indicate that as well.
Are you saying that if the Extreme is in bridge mode connected by ethernet that the ports are not active?
Not at all. What I was trying to say was that the connection from the Extreme to the internet must go through the WAN port, not a LAN port. In a large network, this can happen unintentionally. For instance, suppose a client has Internet sharing enabled and is connected wirelessly to the Extreme and by Ethernet to another router. Then the internet connection from the other router would be shared with the entire subnet, including the Extreme through its LAN port. This could cause problems with the network.
However, with the network setup Jerastan describes, this does not seem to be the cause.

My Time Capsule is giving me a warning that double NAT situation is occurring and recommends that I set it to bridge mode What is all this about please can it be explained in layman's terms and not martian thank you.

You have two devices....the Netgear and Time Capsule both configured to act as routers on the network. You only want one device providing this service.
I suggest that you configure the Time Capsule in Bridge Mode as suggested to eliminate the Double NAT error. Unfortunately, the Guest Network cannot be enabled in this setting.
No other adjustments are needed and everything else will operate normally...and the Time Capsule will still be providing your wireless network signal.
Once the Time Capsule is configured in Bridge Mode, it would be an excellent idea to perform a complete power cycle on the network to allow things to reset properly.
Just power off all devices on the network in any order that you want
Wait a minute
Start the Netgear device first, and let it run a minute by itself
Start the Time Capsule next the same way
Continue starting devices one at a time the same way until everything is powered backup
The other option you have is to "ignore" the error and the light will turn green. The Double NAT error may...or may not cause some issues for you down the line. The next time that you update the Mac operating system, or update the firmware in the Time Capsule, it may likely change the Time Capsule to Bridge Mode automatically.
If your Guest Network "disappears", you will know why this happened, and you will have to manually configure the Time Capsule again in Router Mode to provide DHCP and NAT services.
Double NAT can also cause a slow down of web page loading. You may...or may not....notice this.

DCHP and NAT, or off (Bridge-Mode)?

If I want to connect my MacBook and iPod touch to the internet using the AirPort Express, do I need to set router mode to DCHP and NAT, or off (Bridge-Mode)? I can't seem to get them both happily connected at once. My iPod especially doesn't like being connected now that I played with the settings to get rid of the long-standing flashing amber status.

After I turn it on each time, I need to have my laptop on and open up Safari, before the iPod touch will connect.
Normally, you want to power-up the modem first. Let it initialize for about 10 minutes. Then plug-in your AirPort Express. Give it a couple of minutes to initialize as well. Then power-up any of the other wireless clients.
I need to have my laptop on and open up Safari, before the iPod touch will connect. Otherwise it comes up with a pop-window saying "Authentication required" asking for a username and password, or sometimes it'll say "your password will be sent in the clear" (something like that).
Is your ISP providing you with DSL or ADSL service? These typically require that you first enter your user credentials (username & password) prior to gaining Internet access. If this is the case you will want to configure the AirPort Express to do this for you so you don't have to enter them via the PC.
