One goes to the myth subnet, another to the main server, a third has a number of virtual networks which connect to a switch that basically does 'everything else' that needs just one or two devices, eg the TV STB, the WiFi AP, printers and central heating controls. A fourth is the ZM subnet and the fifth is (at the moment) spare. By doing it this way I can take down most parts woithout affecting any other. It also keeps the traffic isolated.

Many wifi routers have a cute trick called a 'guest network’ which is ideal. It gives internet access to the guest machine, but not lan access.
A bit of foolery, some dyn-dns

Description=ssh tunnel to tigger

ExecStart=/usr/bin/ssh -p 4123 -N -R 1200:localhost:22 -R 4001:localhost:4000 git at tigger.3utilities.com


bingo, solution
(test machine cannot call home
 I can ssh there (I’m also using nomachine to get the desktop on my laptop)


PS if you think I’ve gone mad: there is no git passwd, you must use public key, besides there is nothing there except a bog-standard install.
