Hello,
Network configuration image file: https://ibb.co/ncDTVZ6
I am having Phase 1 IKE auth failed in a IPsec lan to lan between OPNsense firewall and Vigor 2133. I beleive this is happening because the Draytek Vigor 2133 is behind NAT, and it is sending the IP address 192.168.4.254 or 192.168.0.100 instead of the public IP 213.58.24.220. The firewall on one site A is an OPNsense, there I have the option to force the peer or remote identifier, but I need to do the same in the Draytek. I have tried to setup the IPsec lan to lan using both OPENsense firewall with the exact same configuration and it works. But I need to get this working with the Draytek.
