Just curious what others thought. I am running Kerio 2.1.5 on one PC and Filseclab on another but would like to eliminate one of these. I like both of them but I am admittingly not an expert when it comes to firewalls. I am behind a router so what I am primarily concerned with is control over what is connecting out. I know that Kerio runs lighter, but Filseclab is not overly heavy on resources so that is not really an issue. Between only these two firewalls, which would you recommend? It would also be appreciated if you would elaborate as to why you recommend one over the other.
