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 its number. IP protocols numbers include: 47 for GRE
(Generic Routing Encapsulation) and 50 for ESP (Encapsulated
Security Payload). Most settings are done with TCP or UDP ports.
8 Click Add .
Repeat steps 6—8 until you have a list of all the ports and protocols that
this service uses. You can add more than one port and more than one
protocol to a custom service. More ports and protocols can make the
network less secure. Add only the ports and protocols that are necessary.
