ZeroTier site 2 site

[michmoor]

Hello everyone,
Got a strange issue regarding ZT and a site2site set up between 2x OPNsense firewalls (Protectli).
I am currently running ZT between my hosts in the cloud , my smart devices and my OPNsense firewall. Everything works flawlessly, no complaints.
The problem is when I set up my remote Opnsense with ZeroTier. I add it to my NetworkID. I make sure the routes in the cloud controller point to the remote sites LAN using the remote OPNsense ZT IP address. When I send pings the pings go through but after a couple of seconds the pings stop. Restartin the ZT service on the remote side, pings go through but after a while it stops. So I know the configuration is correct because it works briefly but the fact it stops after a few seconds is disappointing. For a quick fix I set up a wireguard site2site between my sites and that has been very stable but I prefer to keep my VPN standard everywhere I use it.
I have seen some postings on GitHub that this is an issue as well as some Reddit post but I want to put something out here a bit more formal to see if anyone has come across this and whats the fix.
