compose 6.7.5 is in the repo now and adds a hyperlink to each tcp port (should skip udp). The hyperlink works just like the kvm plugin - it gets the fqdn of the host from the OMV database. Seems to work better than portainer that on my system is just doing something like this - 0.0.0.0:28080 (which doesn't work).
Weird.... When I click the link, mine tries to go to "openmediavault:port" which fails of course. Is there a setting I'm missing somewhere that it's not going to ip:port?
Portainer, to make the port link work, there is an environment variable you have to set to your server ip, then it works fine.
