I’d like to be able to route between zerotier networks. I end up with single devices being in multiple networks to share resources, especially my own devices for admin purposes but also other devices.
What I’m doing now is I have a ‘service’ network and I have a server that is joined to every network. I enable routing and then add specific routes in zero tier for these other networks. That makes this box a bottleneck that I don’t want but it does allow me to get data between networks without having to have a whole bunch of devices double or triple joined.
