Hi there!
I am using several docker containers on OMV and it now happens, that I need to add virtual IP interfaces for two reasons:
1) While the OMV part is exposed to the net, some services do not need to be.
2) Some services share the same ports and cannot easily be configured to use different ports.
Unfortunately OMV is grabbing all port 80 and 443 on all interfaces automatically and therefore fails to set the configuration, as nginx fails to restart while saving the new configuration.
So I pulled the different entries from the zzz-omv-ngnix and spread them into single manually written configs. But now I cannot delete the old GUI made entries un OMV, as it again fails on saving the new configuration.
Probably it would work, if I stop all docker container and save the configuration, but the openmediavault-webgui config file seems to be re-written frequently while saving all kinds of configuration settings and that the always fails again.
So it would really help to be able to add virtual interfaces in a way that allows to address them for certain parts of OMV.
