I can now communicate between the two PLC´s behind the two bridged RUT 200 and I can reach them from a PC.
My problem is with Iphone and Ipad where I have installed Zerotier and they are activated in the portal but ther is no reach to the RUT network.
Are there any special settings that needs to be done on the device for it to communicate with the zerotier network ?
Have you tried following this section of the article, Bridge configuration?This should allow your end devices to communicate with each other on the same subnet.
Keep in mind to allow ethernet bridging and disabling DHCP on the second router.
