two ethernet gateway possible under UN*X?

[Nick Armitage]

does anyone out there have any experience of running two ethernet cards
in the same machine talking to ( and gatewaying between ) two different
ethernets running TCP/IP?

i am most interested in system V or V.2, but experiences on any version
of UN*X would be gratefully received.

if anyone knows of a site which has done this,  or has any  pointers to
documentation of it either being done,  or saying why it  can't be done,
i would appreciate it.

thanks for your time.
