debian & 2 network interfaces using dhcp

[fgrano]

Hi,
is there any way to use 2 dhcp network interfaces at the same time (and somehow manage to get internet access)? I have the following setup:

               workstations
              /
     firewall1
    /         \
ADSL           Server
    \         /
     firewall2
              \
               workstations

basically I need the Server to be accessible via samba and apache to both workstation-networks, and via apache to the internet while making it impossible for the 2 workstation networks to see eachother.

I can easily make it work while the server is only connected to one of the networks but when I plug in the other I suddenly can't access (ping) the outside world. I guess some routing settings get changed or something when I use dhcp on both interfaces??

Is it possible to make this work?

Post your routing tables and ifconfig from when you are connected to each of the two networks seperately and together, and we can see if we can figure it out.
