Access intranet via L2TP (zywall 110)

Hey there! I managed to set up a L2TP VPN tunnel via the setup guide, and connecting to it works fine. I can access internet remotely via the connection, which is what I want.

However, I can't seem to connect to my server on the network via VPN. I'm pretty sure I need to connect my LAN subnet (192.168.1.X) with the VPN subnet (192.168.100.X) to get this to happen, and that I'm supposed to do this via either a static route or policy route, but I just can't figure out how to do it. Are there any available guides for this, since it seems like a very basic/common thing to do?

    Hi @Ollhax

    Welcome to Zyxel community. :)

    After establishing the L2TP tunnel, the clients are able to access to all the subnets belong to the ZyWALL automatically.

    To understand why your traffic can’t be routed, you can go to packet flow explore and make sure if there’s any route that may affect your L2TP traffic.

    Thanks for your answer! I found the answer here:

    I simply had to connect via IP address and it worked fine.
