Port mapping services

[Brett Glass]

Are the two actually the same protocol? Or is Microsoft's
a case of "embrace and extend?" Why do they use different
port numbers? (The idea of having multiple port numbers
for port mapping seems to defeat the very purpose of having
a mapping service in the first place.)

Also, I'm looking for examples of firewalls that monitor
traffic to and from an RPC server to determine what traffic
to allow through. (They obviously have to do this, since one
can't rely on "well known" ports.)
