No one ever seems to be able to fix the problem.
I did get this working for a short time, but after rebooting both routers, the same problem exists. It seems that both ends show the tunnel active, but there may be a bug of some type that fails to completely create the tunnel routes.

My Configuration:

Two TP-link routers with the WAN’s connected via a switch. The WAN network is publicly connected (12.206.139.224/28) with only a gigabit switch between them.

Router A is the “Main” network and the router A has a LAN IP of 10.1.1.40/16. Client PC-A has a DHCP LAN IP (from tp-link router A) of 10.1.1.100/16 (gateway: 10.1.1.40).

Router B is the “Remote” Location and has a LAN IP of 192.168.150.1/24. Client PC-B has a DHCP LAN IP (from tp-link router B) of 192.168.150.100/24 (gateway: 192.168.150.1).

Both Clients can ping their own gateway TP-Link routers.

Both clients have their IP’s set by DHCP from their respective TP-Link routers. The screenshots show DHCP disabled, but I re-enabled it to make certain that I was not missing something.

Full internet connectivity works for both clients through their respective tp-link routers. So, the Routers have working IP’s and connectivity.

Both routers show that the VPN tunnel is Connected.

But the two clients cannot ping each other. No data will pass over the VPN.
