Yes (or put the amiga in the gateway= line in the pentium's rc.conf).

I had the same problem last week. Unfortunately, I did a lot of
things all at once, so I'm not sure exactly what fixed it!

Try 'route add 10.0.0.1 localhost -interface' on the amiga. I got that
from running "perl /usr/share/examples/ipf/mkfilters".

Yuch. If anything, try 10.0.0.2/32. BTW, when you add routes manually
with your class A ("10") network, you may need to be careful to get
the netmask right. With 192.168.N.n, there's a better chance that the
defaults will magically work.
