The Shiva Lanrover I used a couple of years ago was most definitely a
router. It had three LAN interfaces, plus serial PPP for backup. I don't
remember the model number, but it was sold as a firewall / VPN termination
device.

It definitely did NAT too - the 'inside' and 'dmz' networks we had were on
10.x.x.x addresses, but the outside on public IPs.

Sorry this doesn't help you much, but it might be worth looking into the
documentation a bit more just to make sure.

Incidentally, the difference between a bridge and a router is not to do with
NAT. If your Shiva is a router (which I think it probably is), then the
packets will still be forwarded to your ISP with the source IP address
unchanged, unless NAT is configured.

You can of course just do a direct PPP dialup from your FreeBSD box, which
will solve the problem.
