      Hi,

      Recently my hardware Firewall failed, until the replacement comes I need to get PfSense working, but I am failing. I have three physical connections as follows:
      •LAN
      •DMZ (Opt1)
      •WAN
      I am trying to get Internet connection between the DMZ and WAN using the NAT but cannot get any DMZ server to recieve the Internet. To start with I have fully opened the Rules to allow all traffic (once I have the internet working I will apply the original rules). I can access LAN to DMZ no problem.
      I have provided a NAT:outbound rules as follows:
      •Interface: WAN
      •Source & source port: *
      •Destination & dest port: *
      •NAT address: *
      Note that PfSense can access the Internet fine and performs DNS lookups and pings to google. From the DMZ a trace route to google IP also fails

      Any suggestions?

        Did you try the Automatic outbound NAT rule generation?

          If you are set to manual outbound nat, you will need to add the DMZ network to list. I don't think an any is going to work here. There should be a rule for LAN and one for DMZ. Setting the source as something like DMZnet or LANnet or 10.0.0.0/24 and such.

                Did you setup an allow rule in the OPT1 firewall settings? By default no rule is added and will thus block all connections.
