RE: Port problems

["Walden H. Leverich" <WaldenL@xxxxxxxxxxxxxxx>]

OK, two issues here. 

One, while your network group is correct, 2300 is registered to CVMMON
(http://www.iana.org/assignments/port-numbers) that doesn't mean that
that port can't be used for other uses. The registry is a list of
common-uses, not an exclusive allocation. Now, if they are running
CVMMON I can see more reason for confusion, but still, I don't think you
need the CVMMON port on the HMC, so still no big deal. The registry, and
well-known port numbers are important, but there's no technical reason I
can't run a web server on port 25, or a telnet server on port 80 -- it
might mess with peoples heads, but it's technically allowed.

Now, having said all that. WHY are you trying to have a hole punched in
your firewall for the HMC? Do you have a firewall between your internal
network and the iSeries (iSeries in a bubble?) I can't think of a good
reason to open that port (or most other ports) on the firewall. If
you're trying to access the service from the outside, that's what VPNs
are for.
