I'm having a strange problem using Zoom video conferencing (yeah, I know) inside my network. My girlfriend uses it for university.
We have an RB4011 with up-to-date RouterOS and a pretty tame config -- just a NAT hairpin and some simple port forwarding rules, IP reso's and local DNS entries. Attached to the POE port on the RB4011 is a cAP, which is configured to "WISP AP" in bridge mode using the "Quick Set" menu.
The reason I'm posting here is that it seems as if there is something particular to our network that is causing Zoom is perform poorly. Downloading of other participants' video is fine, and the local video "mirror" rending is smooth (so it's not an encoding issue) [this is also on a brand new Dell laptop]. The issue is that other users see very, very poor video from her that constantly freezes for long periods of time, and Zoom complains about poor/inconsistent connection quality. We have symmetric gigbit that tests at ~200/200 on her Wifi. The interesting thing is: If the laptop is connected to the internet via a (very slow) LTE hotspot, not the local MiktoTik router, the outbound video is fine for the other participants. We also tried using WebRTC (via Google Meet or whatever it's called now) on the local MiktoTik router and that worked just fine.
If there some sort of IP configuration that may be interfering with Zoom's outbound video?
Appreciate the thoughts...
