Region : UnitedStates

Model : TL-ER6120

Hardware Version : V1

Firmware Version :

ISP :

I have a Lan-to-Lan VPN connection that works great when you're at either site of the two connected Lan's, I have an Client-to-Lan L2TP VPN setup to login from Home hoping to be about to access both sites by logging into the one VPN connection, however I'm only able to access the computer on that network that I'm logging into. With the Lan-to-Lan VPN setup shouldn't I be able to access computers across both Lan's?

In general, if you are not getting your desired network access there is either a misconfiguration or hardware/software limitation on the router.
Please describe your network or provide a diagram.

See diagram attached I need the home client pc to be able to access computers across the VPN to the 192.168.10.1 LAN.
Thanks for you're help

You may not transverse the two networks in that manner. IPSec prevents this type of behavior. IPSec encrypts packets from LAN 192.168.12.0/24 and sends them to device with LAN 192.168.10.0/24 to be decrypted and vice versa.
You are connecting by way of a L2TP Server on the device with LAN 192.168.12.0/24 but you are not physically connected to the LAN ports and that is where the packets are expected to come from to be encrypted and sent to device with LAN192.168.10.0/24
Neither of the 2 TL-ER6120 routers acting as peers have policies in place to accomplish what you want.

Acalandi, set the L2TP IP address pool to IPs from subnet 192.168.13.0/24 and modify the site-to-site IPSec policy subnet mask to 192.168.12.0/ 23 on both sides. Then the tunnel will accept packets from L2TP client send to remote branch site.
