For those of you that have ADSL connections but want to deploy a gargoyle router with a single NAT you with need to find a DSL router that can be set into a “simple ADSL modem”.

You can of course put another ADSL router in front of the Gargole router but you will run into issues with 'double NAT' (network address translation). This is where NAT occurs twice, once at the firstADSL router and then again at the Gargoyle router.

To prevent this you can covert a certain routers into a simple ADSL modem.

The benefits of this are that your xDSL Router becomes transparent and your Gargoyle router will obtain your WAN (wide area network) IP address directly. This is useful should you need to port forward or remotely gain access to your network from the internet.

• PPPoE connection (PPPoA is nor suitable)
• Suitable xDSL modem (Netgear DG834)
• Gargole Router with SSH access

Medium linux skills are required as CLI (command line Interface) is needed.
