Hi there !
Can someone tell me what are the network requirements for UDP UNICAST to work corosync ?
I have a tunnel with wireguard between machines and is that ok or it uses some communication on lover level of IP stack - I think wireguard is level 3 protocol .
Thanks !
 
Corosync 3 (in use since PVE 6) is always unicast, no configuration necessary. It should theoretically work over VPN protocols like wireguard, but keep in mind that there are rather strict latency requirements, so it will probably not work reliably over an actual internet/WAN connection.
