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

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

Otherwise, if you cannot 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). Another network segment will connect all of your devices with IP addresses like 192.168.1.XXX

Physical Connections

Connect the Modem LAN port to the Gargoyle WAN port.

Configure Gargoyle
