I followed the official guide for Wireguard site to site VPN.
I have created the Wireguard instances and peers and they are handshaking, but I cannot send/receive to the remote LAN.
Do I need to create a Wireguard interface etc.?
Do I need to create routes somewhere?
The official guide doesn't mention either, but I can't ping the remote OPNSense router via the site to site VPN
(I am configuring it via a dial-in Wireguard VPN which does work fine - separate instance and port).
Any pointers much appreciated.
I just have configured a wireguard site to site tunnel between two OPNSenses and I also followed the official howto.
In my setup, I have 2 WG interfaces, one for the Clients to "dial in" and the other one for the Site-to-Site connection.
You have to create a WG interface for each instance and enable it, if not, it won't work.
