Do I need to specify a dest add in rules & nat?



  • I have a pfsense box working well.
    When creating rules I like to create the NAT separately.
    When creating both rules & NAT I can specify the destination address however I am unsure if I just need to specify for rules, NAT or both?
    If my rules have the dest address locked down is there any advantage in also specifying the dest address in NAT?
    Thanks

    NAT happens before firewall rules are applied so if you are port forwarding, say, WAN address:80 to 192.168.1.100:80 you need to pass traffic to 192.168.1.00:80 on WAN.

    The automatically-generated rules on a port forward will always do the right thing.
