How to disable SonicWall

First try to access
http://www.StupidCensorship.com/
If your admin hasn't updated their SonicWall blocked-site list yet, you can use that site to get around SonicWall.

If that site is blocked, then follow the instructions on Peacefire's page, setting up a circumventor. You can set up the "circumventor" program on your computer, and it will give you a URL that you can use to bypass SonicWall wherever you go.
