This was basically working yesterday, I woke up this morning just to see that my two nodes can’t talk with each other.
Node 1 is at my bare-metal Ubuntu 20.04.1 Desktop (bedroom), IP 192.168.0.10/24 - Zerotier IP - 172.30.89.102/16 - online
Node 2 is at my LXD bare-metal Ubuntu 20.04.1 Container in a PC (garage), IP 192.168.0.11/24 - Zerotier IP - 172.30.201.13/16 - online
They can both ping each other via the LAN’s IP (192.168.0.10 can ping 192.168.0.11), I can ssh between then and there is no iptables/nftables firewall.
But they can not ping each other via Zerotier Network!
I can’t see each other LAN’s IPs at the
zerotier-cli listpeers either.
What to do?
I remember that with Zerotier 1.4.3, when this happened, I could just leave a forever ping running and the link was kept alive… Strategy not working anymore? Seems like…
