Programming devices via ZeroTier

[Ceros2112]

Hello,

I have an installation with one LM5 and three Ip router, with ZeroTier I can reach LM5 via ETS but I can't program devices. In diagnostic I can't reach any of the devices via individual address but if I scan the line I can definitely see them and bus monitor works.

I know that probably is something simple but I can't figure out what the problem is, any ideas?

Thanks
