Hi. I have a Flint 2 Home Router as my Wireguard VPN Server. I also have a Slate AX travel router. When I connect to my travel router as a wireguard client, I’m able to login using my work laptop, and everything runs fine except for my Microsoft Teams. Are there any setting adjustments I can make to get MS Teams working?

Hi

Could you let us know what firmware versions your routers are running?

Perhaps you could first try [SSHing into the Slate AX](https://docs.gl-inet.com/router/en/4/tutorials/ssh_log_in_to_the_router/) and run the following command to see whether it fixes the issue for you:
