Zerotier Firewall Rules

« on: October 14, 2024, 05:46:00 pm »

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?

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.
