Peer Guardian & Peer Block

Peer Guardian for blocking malicious IP floods that intend to disrupt the network,
you can also add other IP's to it to block them entering your room


Here is a tutorial on setting up Peer Gardian


There is an alternative to Peer Guardian, it is Peer Block,
i have tested it and it looks identical to PG, but has been improved to remove the bugs as PG is no longer updated,
here is Peer Block's site, there is a stable version and a betta testing version there, as well as a user guide.
