Subject: linux and 2 LAN-cards ?

Hi,

I'm a linux newbie and have some configuration-probs with the network.
could anyone give some hints to get it working?

normally I used mainboard internal LAN for modemrouter / webaccess only.
out of some configurationproblems I had to remove my additional netgear-
router which was used as hub for my additional terminal-workstations
in my flat. but now it is impossible to do that anymore cause my
webserver will not work when the netgear is between the DSL-modemrouter
and my server. so I decided to try it out with a second LAN card (PCI)
where I tried to connect the netgear as hub.

but what happened was, that all outside access wasn't possible anymore
(for example ping google.de) but access to the dsl-modemrouter was 
possible. ping connection to the netgear was not possible.

what happened? have the both network adapters conflicts on the PCI-bus?
or is this a configuration problem within linux config ?

can anyone tell me what went wrong and how to fix that problem ?

sincerly,
Ralf M.
