Web filter workarounds
 

The title should be rather self-explanatory. My school uses a web filter to filter out most video games sites (GFF excluded thank god) and other sites with questionable material. Previously we could circumvent the filter with a web proxy but now most proxies are blocked too. So does anyone know a gimmick or something to get around a web filter (I believe its installed on the router and not on my computer unfortunately) or some really obscure but working web proxy? One that probably isn't listed on google or something?

I've been using www.vtunnel.com recently for gmail and myspace and it's worked ok most of the time.

I have 2 proxies set up that you can use. I use them while I'm at work ~
