You need to make sure that routing works between the two LANs, then
run the aliasing software at the gateway to the outside world.
Routed is useless as it just runs around deleting static routes, and
enable proxy isn't very useful at all.
Did you add the two ``add <network> HISADDR'' lines I mentioned ? If
you get the two LANs talking, everything else should work fine. Of
course everything on your ``home office'' LAN will need to know how
to route to the ``satellite office'' LAN - you might be able to get
away with setting up a static route on the 'net gateway and letting
the ICMP redirects tell everyone else how to get there, but if you're
using DHCP your best bet is to update everyones routing info.
