So, basically you want to use your dialup connection to serve many
machines, right?

If so:

1) First of all, the machine which runs ppp has to be the default gateway
for every other machine who needs net access.  This way, when network
traffic needs to go somewhere other than the local network, it'll flow out
to the internet.  On NetBSD machines, this can be done by the
"route" command, or by setting /etc/defaultrouter to an IP address of the
default route.

2) The PPP box will most likely have to run NAT, unless all of your other
machines are on registered IPs (unlikely).  Check out the NetBSD
documentation section for a description of firewalls.  It all boils down
to having to add about 3 lines to the /etc/ipnat.conf file.  Easy as pie.

Of course, if you don't want telnet, ftp, etc... access and just want www
access, you could use squid or a similar http proxy.

Hope this helps,
