You can configure TeamViewer to run exclusively within your internal LAN only. That is still either an Ethernet connection (computer connected to switch or router) or a wireless connection.
My setup is such that my observatory computer is firewalled and only specific traffic is allowed in or out. I have allowed connections to TeamViewer to it (it is currently over wireless).
If Simon needs assistance setting up his Ethernet (much more reliable than wireless), I'm sure many of us can assist us. We just need to know what the actual problem is, and, how he is attempting to connect his system.
Let us know, Simon!
