Well, i think this is one of the most frequently asked questions...
For FreeBSD 2.0.5:
add
sysctl -nw net.inet.ip.forwarding=1
somewhere to your /etc/netstart (or /etc/rc.local)
For FreeBSD 2.1:
put
gateway=YES
into your /etc/sysconfig.
Of course, you must make sure that the _outside_ router is willing to
forward all packets for the 200.1.2.* (PPP) network to your box.
Btw., i don't think 200.1.{1,2} are official IP net numbers for you,
so don't use them! Instead, use the reserved networks that are
mentioned in /etc/hosts.
