Routed or bridged mode + licensing question

Hi Cisco ACE gurus,
I have the following questions and I would be grateful if anyone could answer them.
1) As we know the basic license for ACE limits its throughput to 4Gbps. What does it mean? Does it mean that only load balanced traffic is limited (policed) to 4Gbps? Or any other traffic passing through ACE is limited to 4Gbps (from what I know ACE is a cef720 linecard having 20Gbps to a switch fabric)?
My question comes from the following scenario. Let's say ACE is deployed in routed mode and it has 1 client vlan and 2 server vlans. There are VIPs, serverfarms, rservers defined etc.... Now there is a need for a rserver from vlan1 to communicate with a rserver from vlan2 (directly and not through a VIP). In this scenario def gateway of both servers points to ACE (ACE is doing inter-vlan routing).
So in this case in order to allow for that communication I would need to create ACLs and apply them to ACE interfaces.
Does it mean that the traffic would be limited to only 4Gbps?
2) let's say I have 2 DC (2 different geo locations). ACE is located only in one of them. Real servers are dispersed in both of them. ACE is deployed in routed mode. Is it possible to configure ACE in such a scenario (to server VIPs for clients when rservers are in 2 different DC)?
My assumption is that it is possible and in order to do that I would have to use NAT (and source NAT client traffic) so that traffic sent from client to a VIP could be src natted and go to the other DC (through client vlan), reach the rsevers in the other DC and come back.
Is it possible to also do that while ACE is deployed in bridged mode?
While reading about ACE and NAT I came across the sentence "ACE is not able to NAT bridged traffic". What does it mean?
regards

sorry Marko but I am lost. We are talking now about one-armed mode of deployment. There
are 2 contexts and the same vlan is used in both of them (that's why it is shared). In this case I don' understand what you wrote "you have server A in the shared VLAN of context A, you can not reach a VIP from context B" ... that is the same vlan so I can't see any problems..... unless you are describing situation for bridged mode deployment of ACE.

How do I determine if my router is Bridge Mode capable

I have a linksys WRT 54G router that I wish to have Bridge Mode capability. How can I determine if this router has that capability.
Linksys Article ID: 24583 describes the procedure to turn a unit that is bridge mode capable into bridge mode, but which numbered ports of the router have Bridge Mode capability.
Thanks for any help.
Solved!
Go to Solution.

WRT's Linksys firmware doesn't support bridge mode. You will need use a 3rd part firmware like DD-WRT.
Please remember to Kudo those that help you.

Using a Dlink router in bridged mode with Airport Express

I have a broadban connectiond via a Zyxel P-660 wifi modem + router. I have connected the Airport Express to this modem via ethernet and set up a wifi network. The wifi on the Zyxel has been turned off.
Since the wifi signal is weak in the other rooms, I am planning to link up a Dlink DIR-600 router running on the DD-WRT firmware on the bridged mode with the AE.
What settings do I need to have on the Dlink ?

I am planning to link up a Dlink DIR-600 router running on the DD-WRT firmware on the bridged mode with the AE.
If you are planning to have the Dlink device pickup the wireless signal from the AirPort Express and then "repeat" that signal, it is extremely unlikely that this will work.
Apple uses proprietary settings for their "extend" feature, which will only work with other Apple routers. It is....as far as we know....not compatible with devices from other manufacturers.
What settings do I need to have on the Dlink ?
All you can do is try to follow Dlink's instructions to setup the device as a "repeater" or "relay". The DD-WRT Forum might provide some tips. As you might imagine, there will not be much chance of a Dlink user ever seeing your post on an Apple forum.
DD-WRT Forum :: View topic - D-link DIR-600
There are no settings on the AirPort Express to adjust for this other than the obvious setting to check the box next to "Allow this network to be extended" on the Wireless settings page.
Good luck

Airport Extreme ethernet routing in Bridge Mode

i had(!) the following scenario Airport Extreme (5th Generation) .. via WAN connect to the modem, Ethernet to serval switches, WiFi acting as WDS Main
the WDS Slaves are 3 small Airport express and one Airport Extreme (1st Generation)
due a cabeling problem i had to move the WAN Modem .. and connected it to the 1st generation airport extreme created a Joined network (not WDS) enabled DHCP on the same device.
the new Airport extreme (5th generation) and the Airport Express joined the same network and running in bridge mode.
everything works just like before .. all networks parts can connect to each other, anywhere else including the internet.
exept of anything connected to the ethernet ports of the (now slaved) airport extreme (5th generation) anything connected there seems not to be routed at all ..
they have a physical connection (link show on the Airport and on the Switch. but there is zero data going trough ... no DHCP adresses assigned. manually assign a IP in the same network results in the same effect (can't even ping the directly connected Airport Extreme.
is this a Bug ?

oh ic ... thats why it worked before the other way arround ...
well does still not make any sense to me .. but you are 100% right ..
enabeling WDS on the Airport Extreme (1gen) and doing slave the Airport extreme (5 gen) works fine .. but the connection times are about 10 times slower than in a joined network.
which makes the whole show extremly slow ...
it takes some times 5 minutes and a million time clicking (assign new) to just get an IP adress ... even if the dhcp running on the same Airport where the client is connecting to ..
if the 5gen APE is WDS master .. and the 1gen is WDS Slave (my old setup) .. this problem is not existing ...
but then ican't connect the WAN modem to the slaved Airport since the slave is always bridged and the master requires internet connectivity trough the local Wan port
any idea to get arround this ?

No ip with router in bridge mode

i am running a 2009 mac pro, os x server, with some minor and ultimately forgotten changes to unix level services like PHP.
it's been customized, but everything works. Except for one thing, under peculiar circumstances, and I really need help to fix the problem.
here it is as quickly as I can describe it:
I am running an airport extreme router off of my brand new FIOS router (wifi out of the airport). The FIOS router wants the airport in "bridge mode" (if you do not know what bridge mode is, you probably cannot help me,) When I set the airport to bridge mode, my computer cannot get an ip address. it can't see the router, and it doesn't seem to be able to see it at all.
I have 2 computers in addition to this (older mac pro, and a brand new Macbook Air) that don't even need to be nudged. they just work.
I have 3 iDevices that work without complaint as wel.
I also have a wii, a PS3 that, again, without any prodding, accept the change to bridge mode, and get on with it.
can anyone out there suggest any possibilities here?
the only things that are majorly different is that the airport extreme is changed over to bridge mode, and the IP address list is different. (1.92.168... vs the 10.0.1....)
I can work without being in bridge mode, but it robs me of performance, and I like to follow the rules.

Grant, the only true statement was the first one.
the APE is smart enough to do all of the other things you suggest, automatically.
I know that I mentioned that there are a lot of other devices and that They do not have any difficulty when the router is switched into bridge mode. Let me be more sussinct...
No other internet appliance on the network (and there are quite a few) has any difficulty connecting to the internet automatically and without even the slightest adjustment, once the APE is put into bridge mode.
but since I am trying to figure this out, I have more information.
first, my mac pro does seem to have an ip address from the router, in that I was mistaken. It has an IP and it cannot connect to the internet.
second, I decided to try to connect to the FIOS router's wifi directly, to try to determine where the problem is, and it appears that I have the exact same problem directly connected to the Fios Router's wifi.
any inspiration would be appreciated, but I think I might know what is going on. the Mac Pro wants one specific IP address. I think I might have given it a static IP years ago, and there might be some Unixy things I have to do to undo that.

Using an AE as a router? (Bridge Mode?)

We're attending a trade-show in Vegas next week, and the internet is VERY expensive. We're purchasing one "Wireless Code" which means that we get a code to their wireless network. We have 2 wired Mac Minis that we're planning on using. I have both an Airport Extreme, and an Airport Express that I can take with us to the show. My question is, if I'm not connecting to an Apple base-station, am I going to be able to connect the router to the Hotel, and then use the Wired network with the two machines?
I've been playing with the setup, but it looks like I need the MAC address and a few other things I may not have access to.
Thoughts?

If you've got an airport extreme and express, you should be able to get this to work.
You should be able to set your extreme to connect to a wireless network. It will then share the connection to computers on the ethernet port. The only problem I see is that it turns off NAT/DHCP so the airport and the two minis will be requesting IPs from the wireless connection. This may or may not work.
You can probably then attach the express to the extreme and it will give out NAT/DHCP addresses wirelessly to the minis (if necessary).
One other way to get around this without using routers is by connecting just one mac mini to their wireless network. Then choose to share the internet connection over ethernet to the other mini. This will work if they're close. If they're not close, you can connect the express to the first mini's ethernet port and create a new wireless network that's using the mini's shared connection.
Of course, test all this out by connecting to a wireless network somewhere else before going. You should be able to get it working right

Problems connecting airport express a1264 to bt homehub 3 router in bridge mode

I cant seem to get this to work. When i had sky i could bridge my airport express to their router and create a new network so i could extend the network upstairs using another airport express.
I just cant seem to get it to work with the bt homehub 3. can anyone help?

Althrough have no experience of the device this Netgear extender has apparently been used with Home Hub (Ver 2) with success.
Netgear WN1000RP
Every "free Netgear router" i have received from ISPs in the past has been slung in a large box and forgotten.
Much prefer Cisco or Apple with the ISP device simply being a modem.

HH 4 & TP-Link nano router WR702N (bridge mode)

I wonder if anyone can assist. I am trying to set up the tp-link device as a bridge, however whilst my hub recognises it as a device within the home network devices when I try to connect to the bridge it doesn't work.
I have set up the bridge with a static ip and can amend the bridge settings accordingly from this. Having followed the instructions from various sources I'm at a loss as to what I'm doing wrong.
Any advice would be greatly appreciated.

Have you followed the manual supplied by tp-link

Does Bridge Mode Work only with Apple Router?

Can I use an Airport Extreme Router, in Bridge Mode, as a wireless bridge in a network that does not use an Apple Router?
Situation: Wifi Hotspot from Smartphone connects to Dlink Wireless Bridge in other room allowing Wifi access to printers having only Hard-Wired Ethernet connections. Trying to do the same with an Airport Extreme, with same network name and password, in bridge mode, to provide a PC internet access through the Ethernet connection to Airport Extreme. Cannot seem to get the Airport Extreme in Bridge Mode to function as a wireless bridge on this network.

Are both of your AirPort Extreme models the "ac" version?
So Base Station (2) would be set to bridge mode, hard wired to Station (1). Base Station (2) - I believe in this configuration will broadcast the wireless signal from Station (1), the router, with all DHCP addressing handled by Station (1).
No, Base Station 2 would not broadcast the wireless signal from Base Station 1. Base Station 2 would broadcast its own wireless signal, which it derives from the Ethernet connection coming from Base Station 1.
You don't have to worry about "bridge mode" if you use Apple's "wizard" to set things up in AirPort Utility.
If the wireless on Base 2 is configured to use the same wireless network name and password as Base 1, then Base 2 will act like an "extender", and it will seem as if you have one "big" network. This type of setup is called a Roaming Network.
Base Station 2 would only broadcast the wireless signal from Base 1....IF....Base 2 was connecting using wireless. But, you changed the question to ask about Base 1 and Base 2 connecting using Ethernet.

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.

Combination bridged mode routed mode CSM

We run an active/standby pair of
CSM with SSL WS-X6066-SLB-S-K9
currently we have our real servers in 2 vlans: 116 and 117. our VIPS are mostly in the client vlan 119. load balancing works fine.
We now want to load balance between real servers in the 116 vlan. So far we have been unsuccessfull to get it owrking. I suspect because we essentially require a configuration that combines routed with bridged mode.
has any one been able to configure such a setup? Is it possible at all?

This type of topology is not 'bridged mode'.
When you has source and destination of load-balancing process in the same subnet (in your topology vlan116) you need use source NAT (client nat in CSM terminology).
Let me explain it:
1. client (srcIP-vlan116) sedn request to VIP (VIP-vlan116).
2. CSM process (modified) request and send it to dstIP-vlan116 (src IP is srcIP-vlan116) (*)
3. server receive request. It will resopnse to srcIP-vlan116 and response is not delivered through CSM, but direct. TCP communication is not possible, because client's request is modified on the CSM.
* when CSM modify source IP for example to one of IP addresses of CSM, response from server is send always to CSM and not direct.

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.

Airport extreme or netgear 3100 in bridge mode

I have just upgraded to fast internet and Telstra have supplied a Netgear 3100 D modem/router.
This modem is linked to an airport extreme (currently in bridge mode) which is the hardwired to a router (Intelligent) before hard wired to a time capsule and linked wireless airport express to send wireless around house.
my question is, what is the best set up. The netgear modem/router in bridge mode with airport extreme with DHCP and NAT or leaving the modem/router in DHCP and NAT and Airport extreme in bridge?
is one better than the other?
thx

One is not better than the other....unless you require that the AirPort Extreme also provide a Guest Network, which it cannot do in Bridge Mode.
Things will be much simpler though, if you leave the AirPort Extreme in Bridge Mode and let the Telstra provide DHCP and NAT services for the network.

Port forwarding but can only connect to wifi in Bridge Mode

Hi
Our ISP is TalkTalk and we use their Fibre service which connects through a BT Open Reach Modem. The TalkTalk router seemed to causing drop outs in wifi on my macbook pro so I bought an Airport Time Capsule for the wifi router and to back up my mac.
We aren't issued with PPPoE details and the advice from the TalkTalk community was to connect with the Router in Bridge Mode. This has worked a treat with the various Apple and non Apple items we have in out house except one.
We have security cameras which we control through a Windows laptop and can view one out phones. To make this happen we have to set up port forwarding. However, we can't do this as it's in Bridge Mode (as far as I understand).
I'm afraid my knowledge of these things is very basic so I'm hoping that someone will have an easy answer to this. Anyone got any advice on how I can make this pretty white box do its stuff please?
Thanks in advance!
