Alright, I need a firewall with outbound protection, I've narrowed my choices down to Sunbelt/Kerio, or Comodo, that'll work well with gaming/p2p, I've used Sunbelt/kerio for a while but it seemed to hog up resources, but may go back, I don't know, what would be lighter/better?
A linux router such as IPCop, Endian, or Untangle. P2P traffic overwhelms most home grade broadband routers with all the concurrent connections. Having your firewall on its own dedicated hardware eliminates the load on your PC.
Go for outpost firewall it has option to run in Background mode and Running in Entertainment Mode best for low system resources For gaming and p2p setting go to outpost forums....
Even in background/entertain mode, Outpost is still very heavy. This mode just prevents any windows to pop up and annoy you while playing/watching a movie in fullscreen, ect. BUT, the new Outpost security suite 2008 looks promising and by far lighter in memory usage (I've been trying it and I'm a gamer). We should wait for the final version to get released and it will definitely be worth it.
I would rather use looknstop 2.06 because it's light and very efficient. I recommend it with great support. Best Regards.
