I see. So a kind of firewall specifically built for NAT.

IPv4 is a "private network" address -- no idea what part in your installation is setting up that. Perhaps it is ifupdown due to some entry in /etc/network/interfaces? > When I do dhcpcd on the networks, the addresses become the address from > link-local 1 > 65.254.0.0/16. I'm still confused you have dhcp and not dhclient. The former comes with Debian package isc-dhcp-server, which is priority "optional", the latter with isc-dhcp-client, which is "important". And I didn't know the dhcp server can request IP addresses (i.e. playing client). > I can't ping my nameserver, nor can I ping googles nameserver. > It says Destination Host unreachable. In both cases, I assume. What is "your nameserver"? How do you know it? Did it come via DHCP? Is it in your /etc/resolv.conf after "doing dhcp on the networks" > dhclient isnt installed on the Debian CD. Does it make a difference when I > download the Debian DVD? It is in package isc-dhcp-client (see above). I'd expect it to be installed in almost all "normal" installations, since it is priority "important". It /should/ come in the Debian CD. > The 123 IP Addresses were made up. I assumed as much :-) Most of the time, IP addresses aren't very sensitive information, but some people do prefer to hide them: this is to be respected, of course. Now to the next step: what does "ip route show" say? Is there a default router? Can you ping that? Cheers -- t
