Fairly Simple Networking Question

[Fozzy Fozborne]

I don't know if this is possible, but here I go...

 

I was wondering if I could have my PC set up so that it connects directly to the internet through my modem through ethernet, and have my router connected to the second ethernet port on my computer.

 

If it really matters, I have an Asus M2N-SLi Deluxe, a Motorola SB5101 Surfboard Cable Modem, and a Linksys BEFW11S4 Wireless B Router.

 

Diagram for the visual people out there:

 

I've tried to get it working before, but when I try to get on the laptop wirelessly, it doesn't assign an IP to it, it just sits there.

 

What I was thinking about is using a crossover cable to link the second ethernet port to the router.

 

Oh yeah, the reason why I don't want it just going modem->router-> PC/Laptop, is that the router resets itself every night, really annoying.

 

Any ideas?

Let's say that Ethernet Port 1 is "eth0" and Port 2 is "eth1"

 

Basically, what you want to do is to connect to the internet directly through eth0, and then share the connection to your router through the eth1?

 

I don't know much when it comes to networking. First thing I would try is XP ICS, that can be tricky sometimes but is the easiest way, other than having it Router --->PC/Laptop. Still I wouldn't know how that works.

 

Or, if someone knows, a way to stop the router from resetting itself. Is there any specific time?

 

My ideas....

[Fozzy Fozborne]

Yes, that's exactly what I want to do.

 

The router randomly resets itself all the time, for no reason I can tell, wired or wireless.

 

I've tried talking with Linksys, but they have no idea what's wrong with it.

Can you take it to your retailer? If it is on warranty Linksys might want to change it...

 

Have you tried using ICS yet? It's fairly simple:

 

 

First, do what you want to do: Connect your Cable Modem to your PC directly through the first ethernet port. Then connect the router through the second ethernet port. Cable Modem can use a straigth cable, but your PC-->Router will need a cross-over cable.

 

Now go to your Control Panel, Network Connections, and right click on you Cable Modem, then properties:

 

 

Then click advanced, and check the box "Allow other network users to connect through this computer's Internet connection" under Internet Connection Sharing.

 

 

My GUI is in spanish, so this might help:

After that, it should work. BUT, since this is for sharing the connection to another computer, I have no idea if it would work with a router.

I'm using the same setup right now becuase my wireless router won't forward ports.

Alright, thanks guys, I'll throw in a crossover cable when I buy my computer for my school project. Let's just hope it's more reliable now!

Alright, I got my crossover cable, I plugged it in like you said and enabled internet sharing. I go on my laptop and I see "Linksys" and it connects, and I get an IP address. If I try going on the internet, it says "server not found".

 

One weird thing is that I can only enable internet sharing on my second ethernet port, not my first one.

In the browser, try going to http://64.233.187.99/

In the command line, try the following

 

ping google.com

ping 64.233.187.99

 

Each step assumes failure of previous steps.

1) If Google opens in the browser via IP, you have a problem with DNS settings.

2) If ping to google.com works, you have a problem with browser settings.

3) If ping to 64.233.187.99 works, you have problem establishing TCP connection.

4) If none of these work, you cannot send or receive IP packets at all.

 

All of these will have different solutions.

Alright, thanks anyway, but I ordered a Linksys WRT54GL. It's been working perfectly for the past two days (longer then the entire uptime of my old router the 1 1/2 years I owned it LOL).

 

Let's just hope this one lasts longer.

 

THX for your help!
