I'm using a 5268AC gateway with firmware 11.4.1.532484-att, and getting terrible Tmobile VoIP performance when in DMZ+ mode. I have a Ubiquity EdgeRouter 12 as my border router, and using Eero mesh wifi. If I use pinhole mode for my VPNs TMobile VoIP is rock solid. But as soon as I change the Pace to DMZ+ mode, calls drop, one way audio, and other VOIP problems immediately surface.
Over on Reddit a user was saying this was a known problem. Pinhole is working for my two VPNs, so I guess DMZ+ isn't a "requirement" for me. But I'd prefer to control network access via my Edgerouter 12 and have it get my public address.
Is there a solution to my problem or should I just stick with pinholes for my VPNs?
