2 modems, one for stuff the other for other stuff.
« on: July 14, 2011, 07:02:40 AM »
So I've been searching around, and I am still, but I still can't find a suitable solution.
I have 2 modems, lets call them A and B, I am connected to A wireless and B wired.
Both modems have their own internet connection.
So here's what I want to do:
A for browsing and gaming, B for downloading.

As far as I know, I can pretty much leave A untouched but configuring B is my problem.

And by the way, don't lecture me about gaming over wireless, I'm just using it as an example.

Oh well, found out how to do this already. :P

Changing the default gateway for B to something else and configure P2P client to get to there and the rest should work by itself.

The idea is to leave everything as it is on one modem/router, and if both modems or routers have the same default gateway, like you use 192.168.1.1 to reach it, then you'll have to change either one.
Then configure your applications that you want to reach the modem/router with the changed settings.
If you know how to manually configure static IPs for your network then this should be a breeze.

I forgot to mention that I was doing this just out of curiosity and this will be as far as I go.

Is it posible to do something like this having 2 diffrent networks?

Like connecting PC to PC via LAN with like 192.168.1.1 and .2 and still be connected to internet via 10.10.10.1 ?

When I did it when it type www adress it was looking for it at 192., but when i disconnected 192, it was all fine. Like it wouldn't use all avaible interfaces... how to set the default one ?! Is it even posible to config browser to use 10.10.10.1 gate and not the one that is in interface 1 ?

PC to PC?
Was never successful at that.

I would config internet A for download and internet B for upload. This way you can upload at max speed without losing download.

Most of this boils down to how the routing tables for the "client" PC is set-up.

It is easy to add static routes for static destinations that use a specific interface/route.
But having two applications that connect to seemingly random destinations (e.g. a Web-browser and a BitTorrent client.), and let each use a different interface sounds difficult.
I have read that there are (software) firewalls that can be used to mangle packets from certain applications and redirect them to a specific interface.

This should be possible if you make that 10.10.10.1 router the default gateway.
And leave a route for 192.x.x.x destinations on the other interface.
Assuming you are using Windows, the "route" and/or "netsh" command can manipulate the routing tables.

That's probably not such a good idea for BBT torrents.

This is enough to get this done: www.r1ch.net/stuff/forcebindip/

Forget other stuff.
