An IP protocol number is not the same as a TCP or UDP port
number. TCP is IP protocol number 6 and UDP is IP protocol
number 17. If you use an IP protocol that is not TCP or UDP, you
must enter the IP protocol number. IP protocols include: IP
protocol number 47 for Generic Routing Encapsulation (GRE) or IP
protocol number 50 for Encapsulated Security Payload (ESP). IP
protocols that are not TCP or UDP are unusual.
