 ==== Scenario ====
-I have an existing ISP supplied Router/Modem which is already set-up to provide WiFi to the household. Unfortunately, I cannot load Gargoyle directly onto the existing Router/Modem.
+You have an existing ISP supplied Router/Modem which is already set-up to provide an Internet Connection to the household LAN. Unfortunately, You cannot load Gargoyle directly onto the existing Router/Modem.
-I want to introduce a Gargoyle Router because it is awesome.

-Going forward, the most simple setup will see the Gargoyle router doing pretty much everything and the existing ISP supplied Router/Modem demoted to simple modem duties.
+Going forward, the most simple set-up will see the Gargoyle router doing pretty much everything, and the existing ISP supplied Router/Modem demoted to simple modem duties.
+If the modem can be "bridged" (see below) then Gargoyle can do the whole job. If not, then the existing ISP supplied Router/Modem will still handle the ISP connection, and Gargoyle will cover the rest (firewall, DHCP, wifi, quotas, QoS, etc etc). In this case you need to create **two** network segments.
+The **first network segment** comprises the Modem LAN port, a physical cable, and the Gargoyle WAN port. That's it! All devices on this segment will have static IP addresses like 192.168.**0**.XXX (ie ModemLAN=192.168.**0**.1 and GargoyleWAN=192.168.**0**.2). If you need to access the Modem settings, then you can physically connect a Modem LAN port to a PC with static IP = 192.168.**0**.3
+The **second network segment** will comprise the Gargoyle LAN ports (and wifi) and all of your other devices. All devices on this segment will have IP addresses like 192.168.**1**.XXX (ie GargoyleLAN=192.168.**1**.1) assigned by DHCP.

+To Bridge or not to Bridge, that is the question!
-If you are configuring an ADSL modem then it is preferable (if possible) to put the modem into bridge mode; which in effect, will connect Gargoyle directly to your ISP.
