Can believe it that this was the issue (maybe not) because this started by DSM update and did not go away after router change and tried lot of settings. I have tried even remove all NAT port FW rules and keep running only one node on DSM and one rule on router (still issue).
Finally I have Two Greens!!!
Thank you everyone for help and cooperation. Much appreciate

I forgot to tell you to disable all the malware protections in your router. My Asus addons from TrendMicro interfers with the SN too. Please disable the first option too.
Using the same port didnât worked for me. I tried⌠strange. Maybe I missed something, probably with the port forward. Iâll try your way again with the next multinode setup. If you all say itâs working, it must be.
Yep, I am right. Using 28967 for both nodes on the same machine in Docker, Synology NAS, dosenât work for me. I tried. I donât know why dosenât work like you all said, both nodes seem to listen by design to 28967 TCP, but they canât use it both in the same time. I refreshed browser, close it and restarted it (it deletes everything on close); itâs not a visual error. Here are the steps⌠I use putty and sudo su before docker run.
Variant 1:
router port forward: 28967 > 28967 TCP and UDP, 28968 > 28968 TCP and UDP.
docker run ports: node1 - 28967:28967 TCP and UDP, node2 - 28968:28967 TCP and UDP.
Since you already have node listening 28967 externally and you want to run the second node on the same device, for your second node you can use these settings: router 28968->28968, docker 28968:28967/tcp and 28968:28967/udp, dashboard 14003:14002, ADDRESS=external.tld:28968.
Your current variant will work too, if you want to map 28968 to 28968 for the second node instead of 28968:28967, then you need to change the default option server.address: :28967 to server.address: :28968, so the mapping 28968:28968/tcp, 28968:28968:/udp will work too.
