I have several apps that seem to not be able to setup video - namely meet.google.com and WhatsApp. FaceTime works perfectly well. In sniffing around it appears that both of those apps are trying to setup a dynamic UDP port inbound via WebRTC or similar. Essentially this feels like the old VoIP and passive FTP issues of yore. Is there a STUN server one can use with OPNsense? Or is there a built in fix for this? Another fix I haven't considered?

1:1 NAT is not an option as I have all sorts of random devices connecting on the LAN side and this just needs to work dynamically.

EDIT: I should mention, this is on 21.1.4
