Cisco WAN :: Bridge DSL To Ethernet (877)
Jun 22, 2012
I've got an 877 configured and working just fine as a NATing DSL router, but I'd now like to add an ASA beside it. I've got an extra IP from the ISP so what I'd like to do is bridge the DSL interface to one of the switch ports on the 877 and plug the ASA in there.
I've created a bridge group, put the ATM0.1 in it and then tried to put a switchport in it and get:
FastEthernet1 does not support bridging
So, I created an SVI and put that in the bridge-group and added Fa1 as an access member of that VLAN, but nothing seems to come out the interface to the ASA.

Can you use a Cisco 3600 to do a P2P bridge? Using the MAP's ethernet port to connect to a remote LAN? On that remote LAN can you have lightweight APs that connect to a controller on the RAP side?

I'm trying to build a project where I utilize a Cisco 877 as a dumb modem by briding the ATM interface together with an Ethernet interface (VLAN) in this case due L2 switchports.The online documentation for RFC 2684 bridging states that I should be using AAL5SNAP as the encapsulation mechanism however, my ISP requires that I use the AAL5MUX encapsulation as part of the DSL settings.

I have a piece of hardware (audio device) with Ethernet network access only. I'd like to give it to my users and have them connect via Wifi. But configuring a Wifi bridge for each use is too onerous. I'm looking for a wireless bridge device with a display and keypad that allows the user to scan, select and associate with a wifi router, then bridge the wireless network to ethernet so I can attach my device. Does such an animal exist? Price is not a major factor.

I have on my ethernet linux box, that is responsible for IPv6. This box is configured as IPv6 gateway from my network and it also sends RA to the network. All devices on ethernet network can work on IPv6 without problem. Clients, that are connected to WiFi, they just receive the RA from this box -> this packet is sended over WRVS4400N to the wifi network. But all other traffic do not pass the WRVS4400N, so the wifi client is not able to ping the IPv6 gateway. There is no problem on IPv4, there the wifi client is able to communicate with any ethernet device.I have tested WRVS4400N setting "ipv4 only". If I switch on "ipv4 and ipv6", than all devices will get some additional IPv6 adresses and the communication from WiFi client to IPv6 router is not working again. How to configure the WRVS4400N to bridge all IPv6 traffic between WiFi and ethernet?

These questions are only in relation to the above Wireless Router (v6, FW-v1.02 [2010]) :
1. What is an Ethernet Bridge (the basic authoritative definition), and besides gaming, what are they generally used for in a business setting?
2. What are VPN settings in a Router used for, and can a VPN be configured on a remote PC without them?
3. Utilizing bridging, etc., can I utilize my WRT54G as a makeshift Range Expander as long as the primary router doesnt have WEP key requirements? The current WIFI doesnt reach my PC, so I thought I could configure my router midway in hopes of extending the other routers' signal, via some kind of bridging if necessary. Naturally, there would only be a wireless connection between routers.
4. How can I setup a simple Captive Portal on this router?

I have a DAP-1522 in my den that I am connecting as a bridge to a Netgear WNDR3800 that in turn is connected to a cable modem in my living room. I have multiple PC's connected to the DAP-1522 via the Ethernet Ports. All the Ethernet connected PC's are getting IP addresses from my Netgear WNDR3800 via DHCP and can access the Internet fine. The weird thing is the PC's connected to the DAP-1522 through the Ethernet ports can't see each other - they are isolated from each other. I can see the DAP-1522 hard wired PC's from a laptop connected wirelessly through the Netgear WNDR3800 but the PC's wired to the DAP-1522 can't see each or communicate to each other via IP, though they can communicate to anything else on the Netgear WNDR3800 wireless network or Internet.Only the PC's connected to the DAP-1522 via the Ethernet ports are isolated from each other. Very strange. This is a problem because I have a NAS device I want to connect to the DAP-1522 that will be shared by the PCs in my den. I do software development and want access between the PC's and NAS device at Ethernet Gigabit speed. I am using default configurations for the DAP-1522. It appears that firmware for the bridging function if funky. I am on firmware version 1.41. The hardware release is A1.Not sure if it is an issue with the DAP-1522 or the Netgear WNDR3800.

I am trying to bridge internet connection received from my laptop to my desktop with an ethernet cable. Both machines are running win 7.When I try to connect to my local area connection on the desktop most of the time it fails and I'm left with 'Unidentified network' and no internet connection. Sometimes, rarely it does connect properly but I get a notification about there being an IP conflict in the network, but things work as they should.When I diagnose the problem it tells me that "Local Area Connection doesn't have a valid IP configuration"

I have the DIR-655, Rev. B running 2.07NA firmware, and have a strange problem with my wired clients. I have my primary computer/desktop PC connected via wired connection. I also have several wireless clients (laptop, iPad, iPhones, etc.). All have been performing normally. However, in December I connected a wired weather internet bridge to another ethernet port on the DIR-655.
It functions as it is supposed to, and all other connected devices do as well. But here's the problem - whenever I use the desktop PC (the only other wired connection) to do anything on the internet (mostly just web browsing ... I don't stream media from the internet on it, I don't do torrents....nothing out of the ordinary, and nothing really of high bandwidth), the wired weather bridge cannot communicate with its associated website. This continues as long as I'm using the desktop PC. When I stop using the desktop, the weather bridge resumes normally.
I have researched the weather bridge, and it is simply doing POST transactions (or so I'm told) to the website listening to it. It doesn't wait for acknowledgements or anything...just keeps POSTing updates. I tried reserving an IP for the weather bridge and the desktop, enabling QoS, and prioritizing the weather bridge (100 vs. desktop at 125), but it didn't work. I've tried moving the weather bridge into the DMZ. I'm totally baffled how just using the desktop to browse the internet could completely block the traffic from the weather bridge.
On the weather bridge support site, they suggested that I insure I'm not connected in gigabit speeds from my computer to the router, because in the past that has been known to cause issues on clients not running that speed, but I don't think my desktop is connected in that fashion. According to the settings, it can do 10 or 100, full or half. I have it set to AUTO.

I've a WLC 2106 and it is running IOS version 7.0.240. I am trying to setup a wireless mesh and used the Ethernet bridge port on the MAP to extend the network. The wireless mesh works fine but I can not get the switch to work that is connected to the ethernet port on the MAP.I'm using two different Access points. I'm using a Air Cap 3502i as the RAP and a Air Lap1142N as the MAP.The switch port that is connected to the RAP and MAP is configured as the following:
switchport mode trunk
switchport trunk native vlan 2
switchport trunk allowed vlan 10,20,30,40
[code]....
The wireless mesh between the RAP and MAP works fine. I can connect a device to the MAP wirelessly and access the network with no problem but I can not get anything to work that connects to the switch that is connected to the MAP ethernet port.

i am placing a formal request to Cisco and to the firmware development team to create a new-and-improved firmware release for the WET200 wireless Ethernet bridge, a product that is still being produced, shipped, and sold. I purchased the product about one-and-a-half years ago and have enjoyed its performance. There have been, however, some flaws with the device, namely the following:While configured to use WPA2-based security, DHCP-related traffic is not passed from a router/gateway's DHCP Server to connected devices on the WET200. Current firmware release notes indicate this was a known issue and was, supposedly, fixed; however, due to the level of problems customers are reporting, it appears this may have only been resolved, if at all, with security configurations of WPA, WEP, or OPEN. It has not been fixed for customers using WPA2-based security.When I originally purchased the WET200 and configured it to use WPA2-based security, while it, initially, did have a few problems connecting to my router/gateway, it, eventually, did connect and stayed connected for, approximately, one year. However, in September of 2009, it suddenly lost connectivity with my router/gateway and has not been able to establish a connection since, even after reinstalling the latest firmware revision and after several soft and hard resets of the device. I tested the WET200 with another router/gateway, only to experience the same issue. Other devices are connecting to my router/gateway, but, not the WET200. The last firmware update for the WET200 was dated back in July of 2008. Currently, it is January 2010 and since these issues have been known for quite some time, it is unacceptable that the firmware for this device has not been updated in such a long time, especially when there are known issues with the WET200's firmware. Such lack of support is forcing me and my clients to stop using these Cisco-based products and purchase competing hardware, something I would prefer not to do; however, without better support, I and my clients do not have a choice. Expecting me and my clients to use an inferior form of security on the WET200, such as WEP and/or WPA, until a firmware update is issued is unacceptable, especially when that update has not been released in over one-and-a-half years. Such lack of support is especially unforgettable when my clients and I are looking to purchase new networking equipment. In the past, I would not have hesitated to purchase a Cisco-based product; now, with this experience in mind, I am finding it very difficult to recommend to a client that he or she should invest their organization's finances into Cisco-branded equipment. Proper, professional, timely, support of your hardware is expected of your customers, especially if you wish them to remain loyal customers. I have noticed that other similar devices, albeit, higher-end devices, have had their firmware updated, more recently, compared to the WET200. I assumed this meant that the firmware development team was updating all firmware on such devices. So far, I have been disappointed in the lack of firmware updates for the WET200. While I understand the possible desire to update the higher-end products, first, as a professional whose job is to research, recommend, purchase, install,configure, secure, and maintain both the enterprise-level and small business-level devices, I highly encourage Cisco not to overlook their small business products when the firmware development team is updating firmware for any Cisco products. Deficiency in the support of one strata of Cisco-based products is reflective upon the support of any Cisco-based product and is not easily forgiven by Cisco customers, such as myself, when new and additional hardware needs to be purchased.

I curently have 2 Data centers connected with a Metro Ethernet Connection. Each Data Center has 6500 with Sup720s. The Metro Ethernet connection is currently conected by a L3 routed interface. I now need to enable VRFs between the locations and want to determine the best way to adjust the Mero. I was considering adjusting the routed interface to use Ethernet sub-interfaces. Each VRF would be given a different subinterface over the Metro Ethernet connection. I have done this on internal LAN connections but am concerned about exteding across data centers over Metro E.

I am having a problem with my Realtek RTL8168D/8111D PCI-E Gigabit Ethernet NIC. It is not detecting my ethernet cable, and thus leaving me without internet on my desktop, after i updated its driver. The cable is not the problem as I have tested the cable with my laptop. I tried rolling back drivers, doing system restore and removing drivers with driversweeper and letting windows install the drivers again. However, none of these worked for me. I doubt the NIC is faulty as it was working before i updated the drivers. I am using windows 7 home premium 64-bit.

I've had trouble connecting to my own internet and have no wireless. I'm using my neighbor's wireless and it's really slowing her's down. I've tried restarting my laptop (it usually works) and then reinstalled the device under "device manager". It's not the cord, I've checked with my neighbor's laptop and it works fine.I use a Sony Vaio VGN-NS140E with Windows Vista SP2.

I just got a new Xbox today, and use the integrated WiFi card. I was lagging like Crysis 2 on a 6800 GT (forget it). I just got a CAT .5 cable, and plugged it into modem/xbox and IDK... it works, I'm online, but basically my question is:Does ethernet connections have less ping (better) than wireless connections? This is with the Xbox 360 Slim. I know it improves upload, and download, but what about ping?

I have a Dell XPS M1530 with Vista 32 bit. When i plug in a cable i get nothing, no error, and the comp does not recognize that a cable has been plugged in. I think that this started after my Hard drive failed and Dell replaced it but i'm not positive. No errors (? or !) in Device Manager and I can't find the Marvell 88E80XX 10/100 Ethernet Controller in device manager. I have attempted to Reinstall the drivers. The wireless is still working. I have one Light to the right of the port that is on all the time solid but no flashing with the cable in or out.

I've got a router on which I run a backup/media/print server, a couple of computers and a voip box. My router has only four ethernet lan sockets which are thus all occupied by the above, but I need to attach at least one further device b
Secondly, could a splitter such as >> this one << do the job? I'm guessing this basically split a single 4-pair ethernet connection into two 2-pair ethernet connections.

I work for a place that has its own TV broadcast system. From the central site we have contracted fiber connectivity to each of our 10 remote locations. To each location we currently have fiber for data (1Gbps) and fiber to transport our TV channels. Am am looking for a device that can take in our TV channels on coax and give me an rj45 ethernet connection so I can plug the unit into a data switch to use our data fiber for everything (if I need 10 units at the central site to do this, that is fine).taking the ethernet back to coax to distribute TV to all of the TVs in the building. This would eliminate me 10 point to point fiber links.

Is it possible to use a cisco router, in this case a cisco 887, to bridge an external ip address to a device behind the router? I need this because i only get 1 IP Address from my ISP and i want this IP address on my ASA.
I was thinking of a bridge group, but i'm not sure how to go about it! I would like to know if this is possible, and if this is, how should i configure it.

I have a new internet connection. It is displaying lights for DSL, PWR, INET, WLAN.I can connect but it always reads the message "No Internet Access"I went to the service provider to get this fixed. And they created bridge mode through LAN so I could connect using a username and password. (create a new connection > broadband ). But I innocently pressed reset button. I don't want to go back to the service provider to setup the bridge mode or ability to connect by a username/password through LAN.

WCG200 isn't going to connect at blinding speeds, which I'm ok with, I just wanted to know if it's possible?
