How configure network between Router ISP and another Router

[Edgar Oliveira]

Hello everyone,

I am a newbie and enthusiastic guy tech. I need connect my Router, provider my signal of my ISP (Internet Service Provider) with my Router LinkSys - WRK54G.

The Router Linksys has four ports Ethernet and more one port relative Internet. My doubt is how I should configure the cables and Which option I should choose on Linksys. I don't think change anything on router ISP.

If you need the model relative my router ISP please tell me,

Thanks,

Edgar, as I am unaware of that particular Linksys router I don't know what the settings look like and what version you have, you will have to excuse if my answer is a tad Spartan. Also you have not specified how they are connected.
Your ISP's Modem/Router connects to the WAN port on the router. Turn off NAT on the Modem/Router and that should give you a good start. Let us know how it works out.

I prefer my own router to obtain the public IP address on its WAN interface. Most ISP supplied modems are actually "gateways"...they are a combo of a modem and a router. Sometimes called a BRouter (bridge/router). Since broadbamd modems are really bridges.

In order to get the public IP to pass to my own router, most of the ISP supplied "gateways"...have some setting(s) to change to allow them to pass the public IP through to a device connected to them. Bridged mode, or Public IP Subnet mode, or DMZ Plus mode....the wording varies, and the steps you perform vary based on the make/model/firmware version of the ISP supplied gateway.

This avoids the double NAT you'd get if you just uplinked your router to the ISP gateway and you had your network behind your router.

Typically we do this because the router we want to use....is superior to the ISP supplied gateway. I'm not sure this is the case if you have an old wrk54g. You may be putting a bottleneck in the system with that old thing. What is the purpose or reason you want to use it?

If you need to just add wireless...that is a different matter...and there are totally different ways of setting that up.
