The latest Peerguardian for linux is version 1.5, so quite old.
MoBlock is the "unofficial" peerguardian Linux which can handle IP lists in the same format and handles our block and allow lists just as well.
Both do work, but if I remember correctly MoBlock uses less recources ....and it's still maintained, which PG linux isn't.
The link about a gui for PG and Moblock is news to me, might be quite interesting for those preferring a gui to a console app
