Second Wireguard Tunnel uses wrong endpoint

[pr0j3ctx]

Hello,

Package version

1.0.20211208

Firmware version

2.0.9 Hotfix 2

Device

EdgeRouter 4 / 6P / 12 - e300

Description

I am not sure if my problem is a Wireguard problem but I will explain my issue.

I have two DSL Connections. So I use two tunnels (wg221 and wg222) from ER-12 to my Debian Server.
The Debian-Server listen on two ips.
54.1.1.1 and 54.1.1.2

wg221 10.0.0.0/30
Wg222 10.0.0.4/30

The ER-12 has two static routes.
54.1.1.41 via DSL1
54.1.1.42 via DSL2

When Tunnel restarts each one is connected over the right way. After some seconds the second Tunnel (wg222/DSL2) uses the Tunnel IPs from Tunnel 1 for connection.

Endpoint at ER-12 Tunnel 2 is now 10.0.0.1 and endpoint at Debian Server wg222 is 10.0.0.2

route-allowed-ips is set to false.

I have no idea why it comes to this issue.

Can anyone help me or has an idea to solve this issue?

Greats

You are not the only one! I am having the same problem.
Got two tunnels on one machine, connecting to two other machines.
For some reason, after a restart of the machine, the second tunnel shows the endpoint-connection configuration of the first tunnel.
'wg show wg1' shows the config of wg0 in the 'endpoint'-address section.
But if I open the configuration of wg1 in an editor, everything is correct.

And, yeah, before the system restart it worked..
