Problem with 2 Networkinterfaces and DSL (ppoe) on Ubuntu 8.04

[mmetzmac]

Hello,

I have a problem with a.m. configuration.

Situation:

DSL Modem --> (eth1 - UbuntuServer - eth0) --> Switch -- Clients

The ppoe connection is working quite well and I can reach the internet directly from the UbuntuServer. I also can Connect the Clients to the Server. But I can't connect the clients to the internet.

I tried serveral routes, but without success. It would be nice, if someone can help me.

Thanks
Markus

Here is the content of INTERFACES:

> cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static

auto eth1
iface eth1 inet static
broadcast 192.168.2.255

netmask 255.255.255.0
