Hi there, thank-you for the reply.

This is an rdate client accessing a timeserver.

The only only other rules I have are default policies (DROP for INPUT 
and FORWARD, and ACCEPT for OUTPUT), ACCEPT for all loopback traffic, 
and ACCEPT for various incoming ports (eg. HTTP etc.).

It works fine with all rules removed, and it works fine over TCP with 
all rules enabled.

Cheers,
Eric
