ntopng without GeoIP

[rackenthogg]

Hello,

After logging into ntopng web console I was greeted with information that GeoIP support is absent ("Running without Geolocation support ")
I checked https://github.com/ntop/ntopng/blob/dev/doc/README.geolocation.md about how to install GeoIP database manually (I already have it configured correctly for my firewall, but it seems ntopng expects separate database files in .mmdb format).

My question is: are Linux instructions I linked above valid also for OPNsense or is there another way to add current GeoIP database and support to ntopng?
