Using a different ISP

Well, it's as easy as it sounds: Just change your Internet Service Provider! For example only in 'Nordrhein-Westfalen' (a state of Germany) there is a censoring firewall, you can just subscribe to an ISP outside that state. But normally the censorship counts for all the country. One possibility is to try out an ISP outside the country. That costs a lot, but that way you do have a normal Internet access and don't have to worry about getting around filters. This could be a normal dialup provider in an neighbor country or better a 2-way Internet access via satellite like http://www.europeonline.com/, http://www.remoteworkcentral.com/, http://registrierung.tiscali.de/produkte/1400_satellit.php, http://www.gilat.de/, http://www.hns.com/, http://www.vsatnet.com/, http://www.starband.com/, http://www.wildblue.com/, http://www.skycasters.com/, http://www.directduo.com/, http://www.orbitsat.com/, http://www.ottawaonline.com/ and so on, just search with a search engine for '2-way Internet via satellite [your country or neighbor country]' or something like that.
