Sure you could mess around with your router settings, but if you want to do it straight from your PC, then you should use a tool like Peer Block.
If you think about it, this can really come in handy.
Not only does this allow you to make modifications or even branch off into your own project, but it encourages peer review of the code making sure any bugs are eliminated swiftly.
Hosting, as well as the signed driver, is funded by donations from the public.
Future donations are intended to contribute to future signed drivers, hosting and to possibly rent a virtual private server on which the team should be able to build a "real" online-update feature for future releases of Peer Block.
- This fixes a couple bugs, updates some urls, and adds a new feature:- Update servers will be auto-allowed while updating, and then go back to regular settings (ie if they are blocked) when it's done.
this can be turned off via the config file Allow Updates setting, but is not recommended!
