Describe the bug

The community edition of Ntopng allows up to five interfaces to be tracked for monitoring and application features allowed under CE license. https://www.ntop.org/products/traffic-analysis/ntop/

To Reproduce

The Ntopng plugin in OPNSense only allows one interface to be tracked under CE.

Expected behavior

I've manually tried entering additional interfaces in the file "/usr/local/etc/ntopng.conf" and it works for a while but at the next restart the Ntopng goes back to one interface.
