        Basic Wizard

        I always expand the secondary LAN, give it a non-default IP, a /24, and disable the DHCP on it. No reason to use resources.

        You can just ignore the LAN block from Comcast.

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

            This. If you did not ask for your own public IP block, then ignore it. Though it does likely mean you are overpaying for your internet service.

              No, that is not how that works and is not something I care to try and explain.

                You can do that, but you probably don't want that. That's going to be really limiting and really not add any benefit if those machines are not servers. If this was for a DMZ, it would be different.

                    You are trying to use Comcast to host publicly facing servers?

                              he said he wants 10.0.0.1 on eth1. SO I assume Office.

                                If this is both, I'll just assume it is, then you want to make another network for the servers that is a DMZ. Your non-servers (office) will be in a LAN. The public IP block you got will be your DMZ.

                                      DMZ would be another port entirely. This complicates the setup a bit, but isn't horrible. If you have ETH0 set for your WAN, and ETH1 for your LAN (e.g. 10.x.x.x) then ETH2 will be your DMZ.

                                          That would be a common choice, and a good one. So yes. Not a strict requirement, but an easy way to go.
