I keep getting entries in my log showing Blocked packets between an NFS
server and a server trying to automount some home directories.

The strange thing is that there are not port numbers shown, only the
following:

If: WAN
Source: 192.168.2.30
Destination: 10.0.0.57
Proto: UDP

In troubleshooting, I added rules to allow anything from 192.168.2.0/24
to 10.0.0.0/24, but the log entries keep coming, and the mounts don't
work.  Actually, we can mount, but can't ls 

Any help will be greatly appreciated.
