I really become silly now.
I first had a 2.x cluster with 3 nodes.
1 node crashed and it was not possible to remove the crashed node from the cluster.
I tried to setup the node completly new and first it was possible to add the node again to the cluster.
Then the IP addresses and hostnames changed - the result was, that the cluster crashed again.
Now I have installed all without clustering as standalone nodes.
I have added 2 vz containers.
The containers have 10 ip addresses.
From the proxmox server it is possible to reach the nodes:
root@pve1 ~ $ ping 1.2.100.50

From outside it is not possible to reach the ip addresses of the containers ... but! - not all:
I tried a couple of ip addresses all from the same /24 network.
Some are reachable, some not.
I created another vz container with the same problem:
One IP can be reached the other can't.
Every time I boot the host and the nodes other IP addresses become reachable, others are not.
I did not unterstand what happens here.
Any answers would be helpful.
