            Define what you mean by Layer 3 IP, as you have it on a line by itself there so I have no idea what you are referencing.

            But yes, your WAN is eth0, LAN is eth1. If you expand the view on LAN there you can setup the IP and subnet to match your existing LAN networking.

              I HAVE WAN BLOCK....
              LINK IP ADDRESS. X.X.X.240/30
              LAYER 3 IP X.X.X.242
              LAYER 3 SUBNET X.X.X 252

              THEN I HAVE LAN BLOCK
              USABLE IP BLOCK X.X.X.X./27
              USABBLE RANGE X.X.X.X-X.X.X.X.
              USABLE SUBMET MASK X.X.X.224

              IF I CONFIGURE ETH0 AS WAN HOW DO I GET BACK INTO THE ROUTER , I WANT TO HAVE DHCP ON ETH1 10.0.0.1

                Also, I think I see what you mean about bridging. It is in the basic wizard.

                Do not do it.

                Ever.

                    It should go there directly. not sure what you mean by "back in". DHCP isn't needed to access anything.

                      If set by the wizard that way, yes.

                          Is your entire LAN a public network? If not your LAN is a private range that you setup.

                            @scottalanmiller He has his own public IP block. noted as LAN from Comcast.

                                Why do you have a LAN block? What is its purpose?

                                  But why? Is there a purpose to it? You could just not use it.

                                      Then ignore it and set up as usual. you only want that if you REALLY know why, otherwise, ignore it.
