Initial configuration of new installation?

[Lambeth]

Hello

I have recently done a fresh install of OPNsense v19.1.
I am wondering if there is some further configuration that is recommended to do on a fresh install? (Besides the configuration that OPNsense itself does during the installation/initial setup).


I have also looked at all the settings for the firewall and it seems like OPNsense creates a pretty ok configuration.

However, I have noticed one setting which I don't know if it's so good...
In System -> Settings -> Administration, for 'Web GUI' and 'Secure Shell' there's a setting 'Listen Interfaces' which for me by default is "All" (which should mean both WAN and LAN interfaces).

I think I want to change the value of 'Listen Interfaces' to "LAN", as a security precaution so that access is only allowed from LAN, and not from WAN.
