new BB connection: Win boxes OK, but not Linux
 

I have a new BB connection which is mostly working great (so far). But I have a problem with a Linux server. It used to be a dial-up gateway (it's also a mail/print/fileserver), and the Windows clients on my wireless network would connect through it.

Now I have the BB connection going into a DLink DI604 router/firewall. The Linux server connects to the router, as does my WAP. The Windows clients connect via the WAP and router just great. However, the Linux box - which used to be a DNS server for the network - now has trouble itself. I can't nslookup or ping or even get onto the WAN (LAN is OK). Ping and traceroute say "network is unreachable". I've tried putting ntl's DNS servers into my resolv.conf, but I think there's something rather more fundamental going wrong here, since I can't even reach the network!

Any clues anyone? TIA.
