Alright so my work blocks a bunch of websites for obvious reasons. They even blacklisted logmein.com so thats out. I feel that I am capable of getting all my work done AND keeping up with my warfish games once in a while...

I set up a few remote management sites on my home pc for access from work. I have my torrent webui, an ftp site, and remote router management all accessible on different ports and using my no-ip address. All of those sites I can access and play with at my leisure from my corporate pc. I added an app to the list and set up a web proxy (phproxy), but I'm getting smacked with "Access Denied: Proxy Avoidance" when I try to use it. Its obviously determining this from the content of the script or the type of response its getting from the site. I've even tried hosting my web proxy on port 80 to see if it was related to suspicious port communication, but I got the same message.

So my question is, how is the firewall picking up on that? Is there something I can change in the php to counter that? Is there a different protocol/platform I can use for a web proxy that will [probably] get by the filter?

UPDATE:

I have come to the conclusion by the advice of those of the Superuser and Server Fault community that my efforts are a direct violation of company policy and is frowned upon (to put it nicely). I have abandoned my efforts and am now an advocate of working WITH the company rather than against it. I came from years of working for startup companies which had no such policy and I have recently been caged up into a structured, secure environment... I even have to wear dress pants :( I appreciate everyone's advice, especially those who just said "don't do it" in a polite way.
