aniIpFilterIpSourceStart should be configured as well.
           

What is aniDevFilterIpSourceStart?

The lower bound of a TCP/UDP source port range this rule matches, only meaningful when the protocol is TCP, UDP, or TCP-or-UDP; an admin might set this to 1024 to match all ephemeral client ports and above.
