Ah yes Bess Proxy, my old foe. I have many a story fighting her, not many of them successful. However in my later years I have come up with some tricks to deal with that **** (really its a female dog in the picture)
First off, the fastest and simplest way would be to use something like
proxify that gets you around her quickly and effectively.
The next trick would be to manually configure the ip address your computer goes through. Kind of like proxying a proxy. Just look for something like free proxy server on google and a lot of information will come up. Then put that into the options in IE and your home free.
The final trick is that bess doesn't block php boards. Using this you can get to the ns and lm boards with out any problems.
Those are my tricks for dealing with her, and the seem to work effectively. Good luck fighting her tak.
