I must admit that no matter how much I read about firewall rules, it never becomes intuitive or clear to me...so please, if anyone can help me here.
I have a working Wireguard set-up so that I can access my OPNSense router at home from any external location. When I connect, I get access to the LAN, I can manage my router and I can access my NAS via the LAN. However, I cannot access the WAN. I assume I need to add some rule to the firewall, but I really can't figure out how this rule should be defined.
I have attached screenshots of the existing rules for Wireguard and Wireguard (group).
What's in your "AllowedIPs" on the client side?
