Help setting up a 2 router home network

[erbad]

I have one cable modem and am allocated two IP addresses. I also have two routers.

I would like to setup two independent networks where computers on each router cannot talk to computers on the other router. However, computers on both routers would have Internet access.

Both routers would have one of the two DHCP IP addresses provided by my cable provider.

Any thoughts.

Thank you

Assign each a public ip that you are given and plug them in

My cable provider provides with with 2 DHCP Ip addresses, not static. Also, the cable modem that they give me only has one network connection.

That's why I was wondering how to connect these together and get them each to pull one DHCP address each.

I doubt they "give" you two IP addresses. In most cases its an additional service the ISP offers. Have you contacted them for support? Generally you have to run two separate modems.

Is there a specific need/reason to not use one single connection and simply setup two different shares or even use a modem that uses guest accounts?

edit: I stand corrected, depending on the modem and the config. file you can run several IPs through it. I just noticed the mention of up to 5 from places like comcast. You'd likely need switch between the modem routers. The switch would then pass along the separate IP's to your routers and you could go from there.

Actually, yes they do "give" us two IP addresses, it's part of the cable package that I've signed up for.

In terms of why I'd like to do this, it's because I can keep the kids on their own separate Intranet. My Intranet IP provided through the router would be 192.168.1.x and the kids would be on 10.1.1.x

I've set it up this way previously by attaching a switch to the modem and hooking two routers into the switch. However, the switch has failed and I'm wondering if I can daisy chain two routers to accomplish the same job.

Well a router is essentially a switch so you could turn off dhcp on one of the routers. Connect it to the modem and it should allow routing of the two different IPs. You would then connect your second router to the first just as you did your regular switch. You'd likely still need a separate 3rd router for the additional network though.

If bandwidth isn't an issue it might be much simpler to set them up on a single IP and like I said if your router supports it set them up on a guest account

You could setup one router daisy chained behind another router. Where router A connects to your modem and ISP and has private IPs. Then router B is connected via a lan port to router A and router B would then have its own IPs

What two routers do you have? Most likely those soho routers that really dont have any kind of security built on them but hey you never know what you might have!
