 Unless using an external VPN provider, it's best to "nominate" a main router that will produce configuration files.

 +Sometimes, it may occur that from one end of your setup ("A)", you can ping devices and both VPN virtual interfaces at the other end ("B"), however, from end B, you cannot ping the remote router or devices or the client VPN virtual interface at end A.
 +
 +It this occurs, please check that there are default routes setup from B to A. Also, please check that on the client side, (in this case, end B), the "Inbound firewall" option is disabled. On the server side, make sure to add the client's subnet, so it knows how to route traffic from the server back to the client.
