Many thanks to those who responded. I'd have to say I got a mix of
responses on this issue (my original question is posted below). Many
thought that the SS1 was unable to perform this task, many thought it
might be ok. Nonetheless, I'm going to give it a try. I'll start out with
just a stripped down version of SunOS 4.1.x and two interfaces, running a
kernel route table and no fancy software. Now, can anyone tell me who
makes an inexpensive sbus ethenet card that'll run on an ss1? :)

Thanks to the following for their replies:

And thanks to "Herbert Wengatz <>" for telling me to
get lost :)
