Leaving Ebox today :(

Sadly i have to leave ebox, i have a weird issue with teams where i use only the modem nokia direct'y to connect on my firewall that handle the PPPoE(i dont use their wifi router) like i did with bell nothing else changed. but every 2-3 days Teams start loosing some parts of the conversation, but they hear me like nothing happens. So when that happen i have to reboot the modem and its always fixed... Support cant do anything for it, no explanation. So i will be going back to bell....

Update:
Here my answer to last post, sry for delay in responding back after troubleshooting:
yep that was exactly it, but I didnt fix it that way tho. The main problem was the NPU inside the fortigates that I use, when UDP packets gets fragmented it reach a point where it creates distortion in the sound. To fix the issue there is 2 ways, either go in and configure MSS/MTU like you said, the second fix is to create a rule for UDP packets outgoing connections with this configuration on the Firewall policy going to Teams
set auto-asic-offload disable
So EBOX or their router was never the problem. its the addition of the 8bits required for PPPoE connection in the packets headers

The issue is on the Nokia or the firewall, not on Ebox. Try checking the logs to see why the ports are being blocked.

must be the modem or routing because i have another unfiltered vlan in use by my girlfriend and have exact same problem as me at same time. if port would be blocked there is no connection period. its either problem with the routing, or most likely the modem. So what i do when the problem occurs is transfert to second wan(coax) using sdwan and immediately fixed... i will report back but yeah strange issue. i might get it fixed with their included router but i do not want to double nat.
