[ QUOTE ] is it possible to deny skype with astaro?
[/ QUOTE ] look in the ids forums for similar issues with p2p and IM. Skype was founded by the same person who founded Kazaa. Kazaa and others of its ilk know how to find open ports(like port 80) and use it for their comms. The short answer is..not with the firewall. Your best solution is a well laid out and strictly enforced netowrk policy.
