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. Regards, Brian.
