I have a MacBook Pro with the firewall on. I'm trying to run a Wireshark trace and the noise bleeding through Apple's firewall is very distracting. According to the image below, most of this noise is supposed to be blocked.
In practice, I'm finding a lot of Bonjour/mDNS/uPNP traffic getting through. I'd like to shut it down too.
Apple's docs don't really list anything useful for controlling the firewall. For example, there is no
ipfirewall(4) is a programming interface:
$ man -k firewall ip6fw(8) - controlling utility for IPv6 firewall (DEPRECATED) ipfirewall(4) - IP packet filter and traffic accounting ipfw(8) - IP firewall and traffic shaper control program (DEPRECATED)
How does one block all uninitiated inbound traffic, including promiscuous protocols like Bonjour? (I probably need to block outbound traffic too, but I can probably figure it out once I learn how to work with the firewall).
