Can't activate Single Gateway (VPN) for WireGuard

[foobar_infosec]

Describe the bug
I installed VPN clients (OpenConnect and Wireguard) following the publicly available tutorials. But can not activate them under gateways.

To Reproduce
Steps to reproduce the behavior:

Add WG client according to https://docs.opnsense.org/manual/how-tos/wireguard-client-azire.html
- Add gateway
- Try to activate gateway

Expected behavior
- Gateway should be able to activate but is always disabled.

Screenshots
Wireguard client is working:

Relevant log files
I already tried to look at the logs, but they are empty.

File /var/log/gateways.log yielded no results.

Additional context
I tried removing, and creating it new, and I have the same issue with the OpenConnect VPN client, so I assume its no issue with WireGuard but with actual gateway logic.

Environment

OPNsense 19.7.10_1-amd64
FreeBSD 11.2-RELEASE-p16-HBSD
OpenSSL 1.0.2u 20 Dec 2019
AMD GX-412TC SOC (4 cores)

You are missing the gateways IP address for your Wireguard and OpenConnect gateways. They are mandatory to be able to activate the gateway.
