ATMP example

To enable a firewall to allow ATMP traffic, you must provision the firewall to allow inbound and outbound UDP
packets specifically destined for port 5150. The source port may be dynamic, so often it is not useful to apply
a compare function on this portion of the control/negotiation packets. You must also set the firewall to allow
inbound and outbound GRE packets (Protocol 47, Internet Assigned Numbers Document, RFC 1700), enabling
transport of the tunnel payload.
From the Main Menu navigate to Display/Change IP Filter Set, and from the pop-up menu select Basic Firewall.
