Rob, my group has had no problems with running SLIP between a couple of
Suns and a Cisco terminal server.  We ran it with our own home- brew
version of SLIP (according to RFC 1055, of course!)...  to me is sounds
like either the SLIP software is bonkers, or perhaps the Sun configuration
is messed up.  It should definitely NOT be a point- to-point link,
thought, because it isn't.  The SLIP connection should look to your Sun
exactly like the ethernet connection.  The cisco is doing proxy-ARP for
you on it's ethernet interface, so to your Sun it should look like it's
directly connected to the cisco's ethernet.  The cisco tells you the SLIP
address, you should use that address when ifconfig'ing the interface.

To me, this part of your message looks like the problem:
