i use redhat 7.2 and the modem is zyxel 642R-11, its an external modem router for adsl and it is connected through a hub along with the linux and windows boxes.
I use the router as the gateway both for linux and windows, windows work but linux isn;t, i try to use tcpdump in linux, it can sense all the network packets even from outside the internet coming it but linux cannot do any internet stuff, such as ping any ip from the net, browse etc...
My little home network is comprised of the following,
I have a BT Voyager 205 ADSL Router connected to my Phone line.
I have connected this device to a Linksys Wireless Router (Wireless-G 2.4). I manually configured the Linksys to use the BT router as a default gateway. I can connect to the internet with Windows. However when it come to my Mandrake Linux 10.1, the furthest I can get is http'ing the BT device. My network settings are using the address of the Linksys router as a default gateway, the Linksys router uses the BT router as a defualt gateway and the BT router is supposessed to deliver the goods from the internet. This configuration works fine with Windows so what is different with Linux we ask? My thoughts are....My Linux can actually detect my network. The problem obviously lies with the DNS address I use in Linux, until now I was using the same as the one in Windows. which is my default 192.168.1.1 which is my BT router which connects to the WAN address of 86.129.XXX.XXX (don't no uninvited guests!). There are a range of other address which I am going to try. The best thing I can do at the moment is telnet 192.168.1.1 and extract the correct address's the device uses and use these in Linux. Linux is supposed to be more powerfull with its networking features than Windows. Windows relies on this BT device for connectivity wheras Linux is demanding the outside address for itself so it can connect itself without having to rely on a cheap commercial device (I hate the BT device but I'm stuck with it for a year contract!). I intend to crack this problem soon (there is always a way). I will post my results and hopefully be able to offer a helping hand!

It worked!! Whatever device connects to the internet, you must http it or telnet (newbies http). You must find out what address the device uses to connect to external network. I had three parameters,
GATEWAY IP
DNS
SDNS.
I input these details into the internet setting manager and magic!! However, I suggest putting the DNS 1st as it searches this frist and will make browser loading faster.
