Hi Jude and Tim, Jude, thanks for the tip! However, wouldn't a firewall based on iptables be a bit primitive? After all, I guess the only thing I could do would be to block certain ports, so no attack signatures, no intrusion detection etc… However, I checked out Arnos-iptables, but I can't find a package for Mac. Am I missing something? Tim, sorry but I think that's not right, unfortunately. The firewall probably asked you if those programs would be allowed to accept incoming connections, not whether they should be allowed to access the internet. There's a free firewall for the Mac called Little Snitch, but unfortunately that's totally inaccessible. Thanks!
