I read the following form Cisco documentation about IPSec:
"IKE uses UDP port 500. The IPSec ESP and AH protocols use PROTOCOL
numbers 50 and 51. Ensure that your access-list are configured so that
50, 51 and UDP port 500 traffic is not blocked ..."
My question is, what are the PROTOCOL number
Are they not the port numbers?

Hi George, Hi Group,
The protovol-number is a 8-bit field in the IP-Header and defines the
Protocol that the packet encapsulated in the ip-header uses. Common
Protocol Numbers:
1 ICMP
6 TCP
17 UDP
88 IGRP
89 OSPF
You can find the complete reference at
http://www.isi.edu/in-notes/iana/assignme
this field
is called the "Next Header" field.

Or something to that effect.
Just substitute the # of the protocol in where you would normally put "tcp"
or "udp" or "ip".
Hope this helps,
