ZeroTier - Site to Site working but not ssh

[Nitai]

Hi all,

I've got ZeroTier working on all our OPNSense machines, created private networks, and activated ZeroTier. Everything works and finally got the routing working as well.

However, I cannot SSH into any machine over the ZeroTier bridge. I can ping and even access databases (MySQL -host xxxx or mongo -host xxxxx) or Redis across the bridge. But SSH or SCP doesn't work at all.

I'm completely baffled about what is going on here. Does anyone have any hints?

Thank you.

This may be due to firewall rules for the created interfaces...
