Dynamic rule triggers?
-
Is it possible to create dynamic rule triggers in the pfSense GUI? This is common when a state is established when a static rule is satisfied additional ports port rules are established dynamically. This is common for T/FTP proxies where traffic satisfying a pass rule on the control channel dynamically sets up ingress rules for the data channel.
In this case I want to dynamically establish RTP ingress triggered by traffic satisfying a static SIP rule. I know how to do this in pf using anchors and then dynamically adding rules to the anchor, but I don't want to mess with pfSense internal. Should I be looking at writing my own plugin to do this?
