Hello,

the settings of the subnets are all correct, I have just tried it several times (Main-Node: 192.168.xxx.1 and Node1: 192.168.yyy.1). The connection works from xxx to yyy. Meanwhile, VPN is running on Node1 via WireGuard. Everything works without problems.
As soon as the main node is connected to a VPN provider via WireGuard, access to the Node1 network is no longer possible. Tested with ProtonVPN and Trust-Zone.
An exclamation mark is then displayed in GoodCloud for the Site2Site connection.
