Configure Android devices

Due to the complex nature of Android's proxy implementation, the use of PAC files is not supported by default. You might be able to use a third party app however this is not officially supported at the moment. Android support is something we're looking into though. For the more technically inclined, go ahead and see if you can get our PAC file working; if you succeed, let us know. We're interested in solutions that are easy for users to configure and do not require a rooted device (and obviously, if you're an app developer, and wish to publish a solution, your app has to be free).


Configure WRT-based routers

If you don't mind fiddling around with settings then this may be for you. On the SmallNetBuilder.com forums, a member, majika, has written up a guide on how to configure your WRT-based router with Immunicity. Essentially it adds the PAC file to some DHCP options that are often used in corporate environments. Find out at http://forums.smallnetbuilder.com/showpost.php?p=79630&postcount=5.


Proxy Configuration Settings

If you know what you're doing, the PAC file location you need is shown below. This will automatically configure your browser.

You can download it locally, mirror it, etc, but make sure to update it frequently because we often add new sites that are censored.

To check that you've configured it correctly, go to http://check.immunicity.org/ - remember you may need to clear your cache (Shift+F5 in most browsers) if you've visited the check page before.




Immunicity is simple to set up, and doesn't require registration of any kind. It takes less than 2 minutes to configure, and doesn't interfere with your normal browsing.
