First setup steps on pfsense
I've installed the pfsense on a VM and set the WAN and LAN ports so what are the main things to take into consideration at the beginning to be sure that my network is safe.
What are the most important rules or checklist to do?
a default install is safe to protect from outside threads.
there are no important rules or checklists that i know of
As mentioned above, from the WAN side it will be pretty safe out of the box.
My first step even before I connect it to a WAN or LAN would be to change the default password though.
