i want to have my 2 connections, one for internet and one for local network.

i got a evga x58 motherboard with 2 lan connections and i download/upload a lot since i am using mozy for backup to the internet so i want to monitor my internet usage. i also have a network drive that i have all my media on and is a back up for the other computers in the house so it gets a lot of usage.

what i would like to do is have one of the 2 network connections go to the internet only and the other network connection go just to lan devices. basically so i can monitor just internet bandwidth usage.

Based on the info in the question and assuming you have Windows XP systems, below are some solutions I can think of. I also assume that you have basic networking knowledge.

Option 1 - to use a second router, to bypass media pc for internet access on other PCs.

Option 2 - to enable Internet Connection Sharing (ICS) on the media PC and connect directly to the DSL/Cable modem. Connect the second LAN port to a router or switch accordingly.

ICS - http://support.microsoft.com/kb/306126

In both options, you can use Networx for Internet usage monitoring on any LAN interface. I use this free sw and is very good.

Some routers let you configure two different subnets or special routing option. Not sure if yours has that feature. If yes, this could be much simpler.

i was kinda looking for something like change the dns settings on one adapter so it won't use it for the net. something that would change how windows works.

im using a shaplus for the monitor right now and my monthly is already up to 60gb in a week. so i don't know whats local network and whats internet.

sorry about not replying i thought i set up mahalo to email me on reply and never got one.

this is on windows 7 64bit to take advantage of the 6 gigs of ram.

no problem. let me know if this was useful.

DNS settings are for the system and not based on the interface. Routing is based on the default gateway and metrics set for each interface.

So in your case, like @bitmanx commented, you can use netlimiter should work. I tried it and you monitor usage for Internet, local network or the computer. This will also keep the set up simple.

What you are trying to do is called "multihoming". This is pretty complicated to set up... It also may be impossible depending on your NIC card. For this to definitely work you need two physical NIC cards, not just one card with two jacks.

Here's the best link I've found for what to do: http://www.networkworld.com/columnists/2004/110104gearhead.html.

Google windows multihoming for more information.

"For this to definitely work you need two physical NIC cards, not just one card with two jacks. "

Two jacks mean two physical ports with different MAC addresses. so he has what is needed for dual homing.

@gotspeed - Dual homing on the same physical network with the same IP subnet will not work for your requirement, because of the same default gateway for both the adapters.

Here is a support page for Windows on the Expected Behavior of Multiple Adapters on Same Network.

can you provide more info on your network like the router type and how this pc and the others are connected? and also what OS?

You might be able to accomplish what you are looking for by manipulating the route and metrics. You can use "route print" command for this, for help, use "route print /?" command to add/modify the ip routes.

I have never tried dual homing a windows on the same network, so to provide a solution I need more info.

Just use a traffic monitoring app like http://lastbit.com/trafmeter/ or search around for others to monitor network traffic patterns. I highly doubt your saturating a 100mb home network connection and definitely not a 1000mb connection so just use a single NIC port. The second NIC port being redundant the thought of multi-homing is not worth the effort.

good point. I agree with you on using a single NIC to avoid a complex set up and trouble shooting if any issue arises in future.

I dont think the asker is worried about saturating the port, but just wants to monitor the usage.

The sw tool on the link seems to be good and it should work if the requirement is just to see the usage.

Since this is a shareware and $70 to buy, is there a freeware with similar features?

Keeping it all simple you could spend all day looking on http://www.smartcode.com/db/search.php?query=bandwidth+monitoring+control&p=1 trying out tools. Most of the simple one's I loaded were terrible.

There are some other more complex tools that are free but probably not worth the effort. One free one that might work is "NetLimiter 2 Monitor", the free version is at http://www.netlimiter.com/download.php and it even works on Vista.
