the pluto daemon.

Two possible reasons -
 - nothing is listening for connections. Since it works the other way,
presumably pluto is running. Check with 'netstat -anpu' to verify that
it's listening on the correct interface.

 - more likely, you have iptables configured to block incoming
connections to that port. Make sure you're permitting udp port 500 in
your INPUT chain.
