• Hello, i am running in a bit of questioning

    From what i can see PFsense out of the box seem pretty secure as a firewall.

    My interrogation if with some post that i see that mention to block all and then unblock only what you need to pass.

    My setup is the standard one and everything seems to work fine (firewall/Squid/OpenVPN/DHCP AND)
    I want to had a mail server to this config

    Why would i want to go with block all and what would i need to do (firewall rules, NAT) print screen example would be very appreciated to understand correctly  ;)

    My config is a standard one cable modem/2 network cards

    Thank you for all you precious help!
