I've got problem with VPN (Checkpoint); How can I do to filter GRE Protocol with sniffer Pro Lan 4.5.
 
Generic Routing Encapsulation is not defined in the standard protocol "Advanced filter" option (if it would be there it would be under tcp/ip.)
So you will need to make a Data Pattern Match.
Get a trace / frame with GRE in it, and make a Pattern Match and set the data.
