Hi Experts,

I have setup my Notebook, a TECRA M1, to serve as an ISDN Router. Well, actually I'm still working on it, since I can't reach the internet from the client machines.

Here is what I have setup so far:

ISDN Router / Server:
* Toshiba TECRA M1, running Knoppix 3.3 from harddisk
* running Ndiswrapper 0.7 to enable the Centrino PRO2100 wireless network card; setup as Ad-Hoc wireless network
* Installed the ISC Software to setup a DHCP server for the local network over the PRO2100 network card
* Fritz! PCMCIA card to connect to the Internet via ISDN

Client machine:
* Apple iMac running Mac OS X 10.3
* Apple airport wireless network card to connect to the Knoppix ISDN Router

And here is what's working so far:
* DHCP server on the Knoppix ISDN Router is working; ISDN Router is assigne the IP address 192.168.0.1 on the wireless network card
* connection to the internet is established via the ISDN card
* iMac connects to the Knoppix router and gets a local IP address assigned (192.168.0.x)
* I can ping the Knoppix ISDN Router (ping 192.168.0.1)
* I can ping the iMac from the ISDN Router
* I can access the Internet from the Knoppix ISDN Router

And here is what's not working so far:
* I can't access the internet from the client machine (the Apple iMac)

I know that I'm probably missing only one route, but I don't know what route and how to set it up...

Any ideas would be greatly appreciated.
Thx, TorBu


And BTW, here is some more information on my config:
