==== Scenario ====

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. 
You want to introduce a Gargoyle Router because it is awesome.

==== Objective ====

Introduce a new Gargoyle Router into an existing Household network.

==== Approach ====

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. 



==== Prepare a Gargoyle Router ====

[[supported_routers_-_tested_routers | Select a new Router]], and [[install | install Gargoyle]].


==== Reconfigure existing Modem/Router ====

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 in**to bridge** mode; which in effect, will connect Gargoyle directly to your ISP.

Otherwise, if you can**not bridge**, then set the Modem LAN IP Address to **192.168.0.1** to form one node on a very simple network segment just between the Modem and the Gargoyle router (see below).


==== Physical Connections ====

Connect the Modem LAN port to the Gargoyle WAN port.


==== Configure Gargoyle ====

== Gargoyle - Connection - Basic ==


^  To Bridge  ^^  or  ^  not to Bridge  ^^
^  Internet / WAN  ^| ^  Internet / WAN  ^^
| Connect Via: | PPPoE (Wired) | | Connect Via: | Static IP (Wired) |
| User Name: | from ISP | | Static IP: | **192.168.0.2** |
| Password: | from ISP | | Subnet Mask: | 255.255.255.0 |
| Reconnect Mode: | Keep Alive |  | Gateway : | **192.168.0.1** |

^ Local Network / LAN^^
| Router IP: | 192.168.1.1 |
|Subnet Mask: | 255.255.255.0 |
| DNS Servers: | Default DNS Servers Specified by ISP |


== Gargoyle - Connection - DHCP ==

^ DHCP^^
| ☑ LAN DHCP Server Enabled ||
| DHCP range:  \\ Start: \\ End: | \\ 192.168.1.100 \\ 192.168.1.249 |
| Lease Time: | 2 hours |



From here you can [[gargoyle_setup | configure]] other features or [[common_scenarios|scenarios]] as required.
