Are there any firewalls for Linux that will allow one to block certain ports for a specific application while allowing other programs to use the same port, or block Internet access altogether for specific applications?
Everything based on IPTables apparently can only block ports globally for all applications.
SELinux is the only thing I've found so far that might have application-level Internet blocking capability, but it serves a broader array of security purposes and seems too complex for this task.
I don't need interactive popups like with Windows personal firewalls. I'm OK with having to edit a config file. This is for personal desktop Linux use, not a server.
