ICS, Vista and Asus don't play nice

[Planefreak]

I've been messing with my computer and network for a couple hours and have yet to achieve ICS (internet connection sharing). I have the older but still good A8N-SLI board which has two onboard ethernet.

Here's what I'm doing: I have the internet connection running into the Marvell ethernet port, then the other cable going into a router. I know why don't I just set it up to go through the router, right? I'm trying to identify a problem and this seems like a logical way to get rid of one possibility. I have shared the connection that has the internet coming in. Here's where it gets strange. Usually when I have both adapters enabled and connected and ICS enabled, nothing works. Vista can't find the router or access the web. When I just disable the outgoing connection for the other computers both the networks and connects will occasionally show up in one connection.

I reset the dsl modem and router after every change.

Please help

What port are you connected to on the router?

What is the problem you're trying to identify? ICS never works well, and if you're just doing it to troubleshoot there is probably a better way.

I am connecting to the internet port. I'm pretty sure that if I connect to one of the other regular ports that it will require extra setup either in the router or on the other computers.

My internet works intermittently. I am thinking that it is either the router or dsl modem that is causing all of this.

That will not work. ICS is crap at best, and can cause major configuration and IP conflict hassles. You may have 3 DHCP server devices all trying to issue IP's - the modem, ICS, and your router.

The recommended way to use a DSL modem and a 3rd party router is configure your modem to be just a bridge - no PPPoE, no NAT, no nothing. Then the router is used to handle all that. MOST DSL modems provided by ISP's these days are actually combo modem/routers.

I realize that you stated in your first post that you know this is the incorrect way to set things up, but coming from DSL modem to NIC-1 on your PC, then NIC-2 on PC connected to the internet/WAN port on the router is not going to work at all. Your on the right trac that if your having problems with your internet connection, then take the router out of the picture and see if the problem persists so you can isolate the trouble to either the router or the DSL modem or the ISP connection itself. In order to go from DSL modem straight to the PC then out to the router and use ICS, just use the switch ports and do not connect to the internet port at all. As stated above it will not work well but no configuration is necessary in the router cause with that config all you really want is the use the switching capabilities of the router.. HTH

glc: That's basically how I normally have it set up. I'm just troubleshooting for now. I think the two main problems were the IP conflicts and DNS that I seem to run into a lot.

ktkendall: I would love to do that. Except there are three other people in my household who all connect to the router and if the internet is down for 10 minutes they are bugging me and can't live without it.

And, I don't know if I will encounter the problem. It doesn't always happen. Last night it was fine but today I've already reset it a few times.

I can't think of any other way than ICS.

Sorry about that and I must correct myself also in that you are right if you just use the switchports then the other users will have to set static ip addresses on their NIC cards.
