In windows (xp) I have 2 LAN (TCPIP) connections for internet. I want most of my traffic to go over one of them (easily done by setting the interface metric) and then just a few apps to go across the other network. How can I achieve this? I thought of setting up a proxy server that would route over this second network and set my apps to use it. Can you recommend any proxy server that I can setup to route over a given LAN? Is there any better/easier option? Cheers, Daniel

Easy enough to do on a PC-by-PC basis, but by application.....I don't know how you'll do that unless the particular app's reside on a particular PC you can change the Gateway address on.

OSI model. You don't route apps but protocols. How is a proxy, which looks at the protocol level, going to be able to determine what is attached to that protocol? "easily done by setting the interface metric" Doesn't work that way. Metric comes to play when there is a choice of routes. You only have one gateway on your workstations/servers. One gateway = one route. Imagine the power if you knew how to internet search

If the application has a way to configure a proxy then you would be able to do it. Generally only browsers and some linux type programs allow a configuration for proxy. I doubt it would be worth the effort. There are virtual machines and real machines and specialty soho routers that allow one to take advantage of 2 wan connections. What would be the point of having one application use a particular wan? I read it wrong and answer it wrong too. So get off my case you peanut.

This doesn't sounds promising. Ok, here is what I want to do: on my PC (running windows xp), in the office I am connected to the LAN which I use to access the local network and the internet. At the same time, I am connecting my mobile phone (running windows mobile 2006) to the internet (through t mobile web n talk) over the USB port. Given the nature of internet sharing though windows mobile, this creates another LAN connection (TCPIP) and the phone sets itself up as gateway (I think it takes the IP 192.168.0.1). At this point, I think any request I issue will go through my primary LAN (is this because of its interface metric? which by default is lower because it is a 100Mbps connection as opposed to the one to the phone which is 10Mbps?). I want certain applications (let's say something like yahoo messenger, which can be set up to connect through a proxy, and maybe a browser which again can be set up to connect though a proxy) to connect to internet through my phone (instead of the default LAN connection). Can you see any way to do this?
