Sbc Dsl

So I have SBC DSL and I want to use a linux box as a router with two NICs and a simple iptables script. Everything was working great untill it stopped working for no reason.

I had set the DSL up with a windows box and then I plugged the linux box between the DSL modem and the network and I was sharing the connection with my wife like none other.

I have the speed stream 4100 modem that is and you just need to use that as a gateway so the external address of my linux box is, and if you hook it up to a windows box you need to go to and enter your username and password.

I don't have X on the box I want to use for a router, because I want to use it headless, so when I ssh into it and I try "lynx" it doesn't work also "lynx" doesn't work either.

I am sure there is something simple I am overlooking. But it is strange that it was working for a while and then stopped working and now I can't get it to work again. Even if I set it up and connect with a windows box and quickly put the linux box between.

Thanks in advance

I dont really know DSL, never used it or seen it setup, but did you check to see if your external IP from your provider didnt change. If it did your script wont, unless you have your script setup for dynamic external IP's, i think it is refered to IP Masquerading(yes yes, i know i can spell like a champ.

on another not i noticed after reading your post again that you said that your modem has an IP of Well your modem should have an IP like, and than your router should be your gateway at Correct me if I am wrong.

You're not wrong, you're correct. The internal gateway of the DSL modem never changes, which should make this very easy.

The problem is I cannot do

lynx http:

when I need to kickstart the DSL modem. I can not even ping it, I can ping it with a windows machine directly connected to it, could it be biased of my operating system? Maybe I have a bad NIC and I'm beating myself to death.

I actually called technical support and they said they only supported mac and windows, then I told them that they are the loose.
