I just got a new desktop (the client) and hooked my "old" computer (the server) up to it with a crossover cable & NFS while I set up the new system.

Unfortunately, while nfsd is running firefox cannot access the internet through ath0 -- the wifi card (NFS/rpc is on the ethernet card). Do I have to set up a proxy server (eg. squid) or is there a simpler solution?

I don't need direct access to the net on the client. I just want to be able to use the wifi's IP in the server while it has a NFS client on eth0, so that firefox can work online.

Has the Wifi router been set to permit connections from ath0?

Actually, as it turned out someone downstairs was rearranging computers and disconnected the router while I was setting up NFS, so this was a pretty easy problem to fix.

Now I've actually got NFS and squid running on the crossover connection, so firefox runs with http access on both computers, which is nice, plus the file sharing is fine.
