I already setup zerotier with my own controller. For public ip it works great.
I have 2 PC , one at home and one at work.
While using parsec i can connect from my workplace to my home , parsec (from parsec console) can do direct connection to my home public IP (behind NAT)
However, zeroclient peers is stuck in relay condition. Sometimes, it can get direct connection but most of the time it is relay.
Is there any way to debug the issue ? like traceroute command
