Hey
I'm currently setting up OPNsense (v26.7) and WireGuard. The installation of OPNsense is brand new on bare metal.
Currently I'm trying to have at least internet access and access to all LANs.
My network skills are very limited so to lock down LAN again and allow specific LANs/VLANs only etc. will follow after that :)
The connection to wireguard in my home network and extern works without any issues.
The client "AllowedIPs" is set to "0.0.0.0/0, ::/0".
I've no NAT rules yet, only the open port on the WAN interface. And here is where I'm struggling. I created first a "Destination NAT" and chose "Register rule" under "Firewall rule" first which worked too but still no access to the internet or LAN.
I read something about "Source NAT" and to enable "Hybrid Source NAT rule generation".
But it instead of mucking around and enabling and open this and that I would like to ask first to have a proper configuration. The docs are currently for the older versions I assume - https://docs.opnsense.org/manual/how-tos/wireguard-client.html so this doesn't help me at the moment as well.
Anyhow, I hope someone has the time to guide me through my configuration.
Thank you!
Dan
