To enable a firewall to allow ATMP traffic, you must provision the firewall to allow inbound and outbound UDP
packets specifically destined for por t 5150. The source por t may be dynamic, so often it is not useful to apply
a compare function on this por tion 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
transpor t of the tunnel payload.

From the Main Menu navigate to Display/Change IP Filter Set, and from the pop-up menu select Basic Firewall.

Select Display/Change Input Filter.
