NFS and Linux Firewall Conflict

[webmaster at ew3d.com (John Hinton)]

If I run

showmount -e <my_server_ip>

from the client, with the firewall set to on on the server, I get

rpc mount export: RPC: Unable to receive; errno = No route to host

If I turn it off, I can connect.

So far, I have 111 and 2049 tcp and udp open and 4002 udp open.

Anybody know what I'm missing?

Best,
John Hinton
