Ah, right.  I thought I had to touch some file.  I wonder what I was thinking

I assume I'll also need an ifconfig or two to bring up the hme0 interface,

No prob there.  I run ipfilter on my main server, generating the ipf.conf file
with a script, etc.

I have found using ipfilter on my main IRIX server quite easy, but it came
already packaged.  In any case, I have a more complete development environment
on the IRIX box; this Sun thing is pretty stripped-down.

Thanks a ton.
