Firefox as local app and networking

[M Rathburn]

Edubuntu 8.10 amd64

I want to try to run Firefox as a local app on thin clients to see if things
can be sped up (right clicks, listboxes, etc.).  I have everything set up,
unfortunately the thin client running Firefox locally cannot see the
internet.  Here's my config:

eth0 - on my local network where our internet is (192.168.1.25, gw
192.168.1.1).

eth1 - is the thin client network with scheme 192.168.0.254 (server).

I understand -why- it doesn't work.  Just wondering if there's a way to add
a static route/whatever to make it work both ways (internet from the server,
and internet from the thin client's localapps).

Thanks.
