Database
Set the variables to connect to the database. The default values are shown below.

Trusted Reverse Proxies
A comma separated list of trusted reverse proxy IPs or CIDR.
For legacy reasons the default is '*', which means any proxy is allowed.
'**' means trust any proxy up the chain.
APP_TRUSTED_PROXIES=192.168.1.0/24,192.167.8.20
Base url
Set the base url for generated urls. Do not set this if it is not needed.

Generally, LibreNMS will make correct URLs (especially if you have set up your proxy variables correctly)
