Do you know how to find out which ports are open?

Well, there are a few port scanners out there for all OSes that would give you an idea, but if your employer has IDS systems in place, you might get a huge slap on the wrist (or worse) for using them.

One of the easiest ways is to run a web server on alternate ports and try to access then via your browser. Try running one on, say, 4155 (arbitrary number, but it won't be WCCPd - if your place does route vectoring - and will not - by default - go through a proxy - unless your systems are SOCKSified.

You could use netcat - http://netcat.sourceforge.net/ - to open up listening ports as well.

As the previous post stated, however, port 443 is probably a really good choice since it almost has to be allowed (but could be proxied, not just firewalled).
