Setting up a router with DSL 3

[marcvu]

Just wanted to know if it is possible to setup a router with a DSL line or do you have to use the DSL router provided?

 

[jeter]

you do not have to use what they give you. Cisco has a few
routers that will support DSL. Try the 1750. ckeck out site.

Just be careful to match *which* DSL you have.. IDSL, ADSL, RDSL etc..etc..

Need mo infor.

It depends on if you are setting the router up for customers to connect (ie, an isp) or just as a ADSL isp service's customer. Most likely you are the latter. You will need to know the which form you have as the person the answered above stated.

In addition you will need to know what type of modem you have w/ regard to connectivity between router and ADSL modem (some take cross-over,others straight).

Inquire w/ both your telco and isp about the type of service you have and post it here, and I'm sure someone else will be able to assist you further from there.

I thought you can use any cisco router with dual ethernet ports? My friend has a 2621 (dual fastethernet) which haves a dsl circuit going into one ethernet port, works fine. He said the only problem you could have is supporting pppoe.

 

[wybnormal]

Yes the 2621, 2514, 1605 all will work *assuming* you have a DSL modem ( bridge) in place... yes PPPoE is a problem and this is where many of the cheaper routers shine as they have PPPoE support built in. THis would be Linksys, Netgear, Asante and NEXLAND. THis normally comes up with ADSL lines but not always.

I'm currently running the Cisco 827 with the latest IOS and it's rock solid. I've got ADSL connection with Earthlink/Mindspring in Atlanta, GA area running as a PPPoE client. Great router, highly recommended!

Soup- did they provide the router or did you "upgrade" it? Be nice if they did it..

Well, the ISP did provide me a router/ADSL modem (Zyxel Prestige 641) but I went out and bought the Cisco myself. The Zyxel worked ok, but dropped the connection 2 or 3 times throughout the day, which would in turn get me a new IP address. They would not help me figure out the problem because I was only suppose to use it in "bride mode" only, instead I went and hacked away until I got it to negotiate the PPPoE and filtering on my own. The Cisco 827 is definitely a lot more flexible and more robust.

[wybnormal]

bridge mode huh?? that makes it simple for the simple minds on the support side to "troubleshoot" a faulty connection. Congrats on the sucessful hack!!! Any chance of posting the successful config as a FAQ file? It would cool to get a library of these type of configs. Details like provider of DSL etc would be useful.

Soupnazi, would it be possible for you to please post a sample configuration for the Cisco 827 as we are trying to get an 827 to work so we can put in a Novell Bordermanager firewall.

 

[soupnazi]

Here is a modified copy of my running config. I've taken out all the passwords, but left the ip addresses so you can see how it works. The 10.x.x.x net is my home network. The 207.x.x.x addresses are Earthlink dns servers. I also removed all of my filters, but I left the port forwarding entries. This config allows my home pc to run a FTP (port 21) and

http://WWW (port

80) server. Good luck!!

Hi Soupnazi, thanks for the info. We now have a running 827, that our ISP couldn't get to work.

 

[soupnazi]

Congratulations!!
Glad I was able to help! -soupnazi-

Can you surf the web using the FTP & Web Server?

I have a similar configuration, but my Web/FTP Server cannot be used to surf the web but can be access through the web. I cannot seem to figure out how to make NAT work on that server and still be seen from the internet.

 

[soupnazi]

Hmmmm... that's strange. Make sure your PC has the IP address of the router set as your default gateway. In my case, my home PC is 10.0.0.2 with gateway of 10.0.0.1 Also, do you have any outgoing filters in place? You may want to look at that as well. -soupnazi-

Can someone help ? This is my config..When I turn on my PC and router I am able to browse the net, check email, and ping from Dos for about 5 minutes. After that I can only ping from the router. Can anyone see anything wrong with my config.

try on the ethernet port of 199.x.x.x

no keepalive

It sounds like the ethernet port wants a keep alive but the provider is not sending it.. hence the port times out

[Alritter]

The info that I provided you was in regards to my PC. I tried the connection from my laptop and did not experience any problems. Strange to me. They are both running win2k.
Any clues ?

 

[wybnormal]

Does your PC have the correct default gateway set up? It should be pointing to the router. Can you run PING constantly.. using -t ? ping -t target

If that works, then something is timing in the ARP cache would be my guess.. the ping would refresh it.
