Re: TuxGuardian - application based firewall
Don't know about gaming, but Skype works just fine with UFW in a default-deny configuration. That is to say, if the connection is initiated by the user on the client side, then the established and related connections will work just fine. It just doesn't allow unsolicited connections to be initiated from external devices. For Skype, all I have to do is start the client and sign in; no need to open any ports or anything like that. I don't deny anything on the egress side since the only things that connect that way are things that I've started in the first place. Denying outbound traffic doesn't really improve security (on the Linux desktop), but can restrict functionality greatly, or worse, can lead users to make granular changes which undermine whatever protection they thought they were setting up in the first place.
