I know Cisco used 4500 UDP to capsulate ESP over a NAT device.


Checkpoint seem to use 2746. But later verison use 4500 same as Cisco/Juniper. Can anyone confirm IEFT port is the industry standard? I guess 4500.


Strange question but something I need to know..

I guess checkpoint R55/56 using 2746 and then changing to 4500 in the R60 release would indicate a move to the industry standard.


I only ask because I have a client using old checkpoint over a CBAC/NAT 1800 and have all kinds of trouble. This doesnt appear to be the case with the later client which works more like the cisco using 4500.
