Are sure it's NAT on your RB who's blocking? It could be your ISP as well ...

I was trying to check with tool one of them and saw it on Tourch screen.
I am just not sure is it router or actual device (Synology NAS) issue.

If you suspect Synology problem, test on the same LAN. If it doesn't work, then you found it.

I haven't read all of your export but make sure your firewall accepts the redirected traffic. I've seen many people think that a simple dst-nat is an implicit accept through the FW.

Cheers,

Thank you, are you absolutely right! I determined with your proposal that it's my Synology fault, LAN did not pass port check. I was able to solve this issue with proper Docker ports configuration and careful reading of another service documentation.

Thank you again!
