Potential issues with Wireguard?

[DavidGarciaCat]

Hey, guys,

I have noticed two points when trying to use WireGuard with my Umbrel Home:

1. The configuration file points to umbrel.local:51820, meaning any external connection will never occur because that's an inaccessible endpoint if I'm not at home. It would be convenient to explain how we can create an out-home accessible endpoint so our devices can connect when we're in a hotel or anywhere else. Can the Cloudflare Tunnel App help here? But I saw we can only define TCP connections, not UDP.

2. WireGuard usually works with TCP/UDP protocols and port 51820. To prevent unexpected issues, maybe adding a note in the App description informing the user that they will need to open this port in their router/firewall would be convenient.

Cheers,
