Zerotier plugin cpu issues

Hi,
wanted to confirm if anyone else has notice this.
When using 2 OPNsense devices connected with a Zerotier tunnel, cpu will randomly spike to 100% during long periods, and start dropping packets.
The process is /usr/local/sbin/zerotier-one /var/db/zerotier-one/{zerotier-one}
It doesn't happen with 1 OPNsense & 1 Openwrt devices connected.

Do you have routes setup between the LANs of the two OPNsense boxes over ZeroTier? If so, this is a known issue with ZeroTier where it attempts to use the LAN address instead of the WAN address for communication, then fails, then reverts back to WAN. This flapping back and forth causes dropped packets and CPU spikes.

Hi Drakrain,
yes I do, thats the purpose of the vpn on a router for me. Incredible this is a known unresolved issue.
I'll check that, myabe I should go back to the old good OPENVPN.
Thank you so much, as I didn't find this bug report myself.
