I am having a smiliar problem, (least I think I am) no error, just other
machines don't seem to see the outside world. I snarfed up the
ppp+packetAlias1.9 package, and proceded to compile it under 2.1.6.  I
then ran the generated ppp from that directory using ./ppp -alias (so I
wouldn't run the /usr/sbin/ppp version)  I then brought up the link by
hand using the term feature, and verified that from the 2.1.6 machine I
could use the link to connect to the internet.  So far so good, but now
neither the NeXT's or the Macs on my local network could see beyond the
local network.  I am pretty sure that I have the Mac set up correctly, it
was set up for a ppp link, so all the name server and other stuff was ok,
I merely changed it to use the ethernet instead of ppp (giving it an
address and subnet apropriate for my local network), and set up the 2.1.6
machine as the default router.  My mac can see the 2.1.6 machine, but it
can't see beyond.  Any body have any suggestions?  Does the gateway option
in sysconfig have to be set for NAT/ip aliasing to work?  Do you have to
be using 10.0.0.x addresses on your local net?  I read the ReadMe several
times and tried to find further information on the web site, but so far
nothing has seemed to help.
