I am trying to implement a VPN (device to device) from one office (192.168.20.64-127 subnet 255.255.255.192) to the other office (192.168.20.128-191 subnet 255.255.255.192). The devices have been configured, and the policies have been created, but the tunnel never gets initiated.
I ran this by someone that's told me that I'd at least have to change the subnet of one office, in order to get it to work. Is this true?
If both networks are going to route requests for the other network through the vpn device (router), because they are addresses outside of their range, how could this be true?
Thank you in advance.
