The IP protocol 54 is NBMA Next Hop Resolution Protocol, this protocol is used to find out tyhe shortest way between two points and is used by some routing protocol, I am not sure, maybe the OSPF or something similar. We got regular calls here using this protocol, but do not allow it to pass our firewall. This obviously means that the calls cannot complete their task - to find out the shortest way to reach our services to the Internet. And I should like a discussion on this IP protocol to find out if there are some advantages to us to allow it or if it can act as an entry of misuse to map our site, thus possibly generating information to penetrate our site. I bounce a few packets for it every month.
