I am trying to resurrect a once working VPN between two Sonicwall devices. The branch office is the initiator and sends the request, the main office drops the packets and signals an error:
IKE Initiator drop: VPN tunnel end point does not match configured VPN Policy Bound to scope
Have you seen this error before? Can you suggest what to do about it?
More details on the configuration. I assume nothing has changed on the main office configuration. I have changed things in the branch office.
The branch office has two local networks, a local one for the office devices (printer etc) and a second one for the VPN. It has only one public IP on the modem/router/all in one. The Sonicwall manages the VPN but has to go through the local network out to the modem.
=----= printer, wifi modem+LAN(10.X.X.X) =----= X1-Sonicwall-VPN-X0 (192.168.X.X) =--= Tunnelling PCs
The modem is doing NAT for the local network, and the Sonicwall is doing NAT for its own network.
