Zerotier Firewall Rules

[jmcgee]

I cannot connect my Android to Opnsense using Zerotier.  Both devices show up on Zerotier portal as connected and on the Zerotier forum I was told this was a firewall issue.

I have opened up the firewall as follows in these screenshots.  any idea on what the problem is?

could the difference be that opnsense is behind Tmobile CGNAT.  And tmobile phone is not.

As always: check the firewall live log and filter by interface. I assume that Zerotier address as source is not correct. I think this is an automatically created alias by OPNsense for the local interface address. Change it to any for a moment and check again. Always enable logging on your rules.
