I am in college at a university. We have a class B address, and we are
an engineering/technical college. I am about to graduate as a computer
engineer w/ a minor in computer security. Now surprisingly, I have a
task I can't do. The local intranet here is completely wide open to
everyone else on the LAN. It is up to the end user to protect ones self
from any other user on the LAN. But the college has a firewall/proxy
set up to allow internet access out and in and protect the internal LAN
all at the same time. Now most programs I use work fine. But there are
a few that are not allowed, but I can redirect them using a different
port if I want. I am on the internal LAN, is there a way of detecting
exactly what ports on the firewall are open - incoming and outgoing?
Kinda like a firewall port scanner? You have to telnet into the
firewall to even get internet access at all.
