I have several apps that fail to setup video. Audio typically works. What'sApp and FaceTime are the main offenders. Zoom seems to be fine. Has anyone had experience with this? Any fixes? This feels like a similar issue to SIP back in the day where the media portion of the call is not setting up properly as there is no proxy. But every consumer cheapo router works with these protocols, so I am sure OPNSense can as well. I'm on 21.1.8 FWIW. Thoughts?

Will be a problem with RTP traffic.
But we need more informations
- network plan
- rule overview
- nat settings
Network plan wise, there isn't much to it. NAT wise, it is the default out of the box NAT. It is set to hybrid NAT for a Wireguard tunnel, but this all goes through the primary NAT through the primary gateway created out of the box. The traffic originates on the out of the box LAN too.

create a network plan
And what kind of router/modem,... is in front of your opnsense ?
Network plan:
Client > 16 port switch > LAN port > OPNSense > WAN port > Modem
The modem is ISP supplied CPE... an Arris something. It is set to bridge mode and the OPNSense holds the IP. There is no double NAT if that is what you were after.
My setup is very similar with the addition of eeros as Access Points in bridged mode for the wifi clients.
No problems here with video over wifi or wired. MS Teams, Zoom, WhatsApp, all work fine.
I have Unbound doing DHCP server duties, a pihole and Stubby for DoT by the way that could have complicated the setup. No IPv6 just 4. I hope this helps.
That's actually quite helpful in that it makes me want to do a pcap and dig deeper. This is going to turn out to be something stupid I've overlooked I bet.
If you want me to check any settings to compare, just let me know. I'm on 21.1.8_1-amd64 too.
