Hi Mike -
22, but they are having you change it to 80. So just blocking that port
won't work. You I believe you have to filter the packets?
I don't know what they use on our internet gateway, but I do know that if
it doesn't like what it sees on port 80, it blocks it. I found this out
when using telnet on port 80 to emulate a browser so I could see the raw
data coming back to diagnose a problem. Forgetting to put in any little
thing, even if a webserver would have accepted the request, caused the
firewall to issue an error message and drop the connection.
So I really doubt that SSH on port 80 or IRC on port 80 or any of that kind
of underhanded stuff would get through. The people who code the high-end
enterprise firewalls aren't stupid.
