Any ideas?

Rather a suggestion. You could trace relevant traffic with a packet
sniffer and/or iptables LOG rules and try to see what's going on.
Disable all filtering and check if it works. Does the rdate server
accept UDP queries ?

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
