If I initiate a tcpdump on node 2 and start either a netcat or nmap I see<br>
packet arrives to destination host for port 5405 UDP traffic<br>
<br>
<br>
<br>
I do see Corosync listening on the IP/PORT<br>
<br>
<br>
<br>
<br>
<br>
root@node-2:/home/dinor# netstat -an | grep -i 5405<br>

<br>
<br>
<br>
<br>
<br>
On node 1 I start a netcat to port 5405 via udp<br>
<br>
<br>
<br>
netcat -D -4 -u 10.1.0.7 5405<br>
<br>
<br>
<br>
In here you type some text and hit enter<br>
<br>
<br>
<br>
On node 1 tcpdump we see data sent to IP 10.1.0.7<br>
<br>
<br>
<br>
root@node-1:/var/log/corosync# tcpdump -n udp port 5405<br>
<br>

<br>
<br>
<br>
<br>
<br>
<br>
<br>
On node 2 tcpdump I see the data arrive<br>
<br>
<br>
<br>
root@node-2:/var/log/corosync# tcpdump -n udp port 5405<br>
<br>
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode<br>

<br>
<br>
<br>
<br>
<br>
Tested also sending UDP packets from node 2 ? all ok.<br>
<br>
<br>
<br>
So connectivity seems to be ok.<br>
<br>
<br>
<br>
Port scanner also shows the port as Open<br>
<br>
<br>
<br>
<br>

No, it is "ip addr show" output.<br>

<br>
And as long as you actually use those "label"s,<br>
you then can even see these with "ifconfig tap0:jan".<br>
