- so nodelist is defenitely enough, and totem->interface->member is
deprecated.
So, am I at least right that the configuration with UDPu SHOULD work with
geo-distributed nodes with only public IP addresses and no private/virtual
subnetwork? If yes, how could I debug it?
Here's some more info (x.x.x.x is a public IP associated to node1):
