If you are using ipsec then UDP500 is only used for IKE negtations afterwards the encrypted packets are ESP that is type 53 NOT UDP, NOT TCP but ESP. If you have NAT-T patches at both ends then you don't see ESP but UDP2500. Regards Robin On Wednesday 10 November 2004 18:25, Grant Sewell wrote:

This is what I would like to do. Anyone know what port number I should be forwarding?Damn it! Would it be TCP+UDP 500, by any chance? The "iptables -L" output didn't give the port number - it gave the port name! I really should check the /etc/services file more often! Cheers.
