The tunneling firmware currently must be installed on the WAN side of a mesh node. I have two mesh systems, one in MN and one in HI. I would like to co0nnect them with a VPN tunnel. I am currently in Hilo, HI and have been trying to install the tunnel client in one of my MN nodes. How can I do so if I cannot gain physical access to the hardware and connect to the WAN port? The node is located at the QTH of a nearby ham who knows nothing about mesh. That node is my gateway to the internet for that mesh. I can access the mesh using Teamviewer, but the gateway routes me to a computer that is connected to the LAN side of  the mesh nodes. SSN connects to the desired node, but from the LAN side, the website cannot be accessed and the installation cannot proceed.

Is there another way that I can install the client on the node in MN remotely? BTW - My knowledge of Linux is rather limited, but I do have access to an expert here in Hilo.
