Hello, I've decided to try Ghostwall, I haven't installed it yet but it seems like a very good firewall to me. There's one problem though, I'm scared of rule-based firewalls. I feel like I have less control over my internet connection (which isn't really true, but I kind of feel like that), simply because I don't master rulemaking yet. Now, I know how to forward ports on routers, that's really easy. Is forwarding ports on routers comparable to making rules in Ghostwall? So, if I want to block a certain app, I just search for what ports it's using and block those ports? And what if I don't know the app ports, is there some kind of log I can check? Or is there another way of finding out which ports are being used (since when it's already in the log file, there has already been made a connection and I could be in danger!)?
