Does NAT Outbound require WAN rules?



  • Hi,

    If I create a NAT:Outbound rule to allow traffic out via the WAN from the LAN, do I also require firewall rules on the WAN interface?

    I assumed that I had to allow traffic on the LAN and WAN interface settings, but a recent test seems to indicate it is only the LAN I need rules on.

    Should the only rules on the WAN interface be for inbound connections?  Does a NAT:Outbound rule count as a firewall rule on the WAN interface already?

    Regards,
    Rob.

    No. Create firewall rules on source interface. If the traffic is from lan to wan, create the rule on lan.



  • Thanks, that saves me on a lot of extra rules with no purpose.
