If you can do that you'll be golden. GRE doesn't run over a port, it's a Layer 4 (transport) protocol. Oooo, how I hate it when people try to make the IP stack line up with the OSI model... :-) They are *incompatible*. THe OSI model is pretty much a load of BS. 3 layers can be condensed to about 1 and one of them just doesn't exist. SNMP is 161. That is port 161 in both UDP and TCP.
