No, you are not "out there". Simple actually, Your linux box gets two
nics, one has the assigned IP, the other has the gateway IP on your
unpublished subnet. Get each interface working and verify that they are
set up correctly. You recompile the kernel to enable masq, firewalling
ect. You then write a simple script that puts in place /sbin/ipfwadm
rulls, such as:
ipfwadm -F -a m -P tcp -S "$LOCALNET" -D "$ANYWHERE"
ipfwadm -F -a m -P udp -S "$LOCALNET" -D "$ANYWHERE"
ipfwadm -F -a deny -S "$ANYWHERE" -D "$ANYWHERE" -o
Along the way, you will get stuck, but you will find the answer.
