I'm running OMV4 in virtualbox on a windows machine. The virtualbox network uses a bridged adapter, the OMV machine always receives the same IP address 192.168.0.115 from the router.
I've put the WebGUI on port 6003 in general settings. And entered these details for IPv4 Interface: Method:static, Address:192.168.0.115, Netmask:255.255.255.0, default gateway 192.168.0.2(=router) and DNS 220.127.116.11
On this windows machine, I can access the OMV WebGUI on 192.168.0.115:6003.
I've enabled Port Forwarding on the router, directing TCP on port 6003 to 192.168.0.115 on port 6003.
However, I'm unable to reach the webgui (or any other OMV service) through the <public IP address>:6003
What extra steps should I take to make services running on OMV in a virtualbox reachable from outside the network?
