I have a ZeroTier Central managed network I use essentially to access some servers (behind a firewall) from outside.
In particular I have a Host machine (Debian Linux) hosting a few VirtualBox Virtual Machines.
I have ZeroTier installed on Host and on one of the VMs.
I can access both from home on the same ZT net.
So far, so good.
Today I noticed the two machines (Host and VM) seem unable to communicate with each other.
This is not really important because I have other means to have them communicate, but I’m surprised and curious.
How can I debug this situation?
Is it a symptom of some misconfiguration?
Thanks in Advance
