Windows Server 2008 R2: how to start torrents (separate program/ports) via Yota modem instead of wired connection?

Question

Yota

Hello.
There is an ASUS RT-N16 router with a modem from Rostelecom. Distributes the Internet to everyone via WiFi / Wituha, including the server. Recently, Yota appeared as an additional channel, I want to download and distribute torrents through it so as not to clog ADSL for surfing.
In a good way, it seems to me, you need to reflash the router to DD-WRT and dig already there, but there is no time and desire to do this yet. Is there a way to achieve this effect by connecting the modem directly to the server? I would like to start all torrents (for example, requests for large ports / from given programs) through Yota, and not ADSL (which is distributed via LAN). Used by BitComet / uTorrent

Answer 1

Since connections will be established each time with different IP addresses, all traffic will go through the default gateway, which is set at the system level. As far as I know, it is not possible to set a specific default gateway for a specific program.
As an option, I would create a virtual machine specifically for torrents and let all its traffic go through the iot interface.

Answer 2

If torrents work on the local machine, then the option is to install a torrent client that can choose the interface on which it binds and bind it to the modem interface.
If torrents work on other machines in LAN, then install a proxy server on the server, bind it to the modem interface / address, configure the proxy server in torrents + configure port forwarding either using the proxy server or RRAS tools.

I can’t check on win 2k8 server, but on XP I once did something like this (if I correctly understood the task itself).
At that time, ADSL speeds left much to be desired, unlimited was worth a lot, so there was a tariff with a limited speed for external resources and a high speed for internal ones. The provider gave out 2 pairs of login / password, for external and FOS.
I bought a router, set up 2 simultaneous connections there: one bridge (external) and PPoE, it seems that's what it was called in the menu (for FOS), i.e. when the modem was turned on, it raised the connection itself, the computer only consumed it.
I set up a connection for the bridge on my computer, but in this form, after raising the connection for the external network, the entire Internet went through it. To do this, on a computer (winXP) did the following (win + r -> cmd):
route print
I received a list of interfaces, something similar to 0x1, 0x2 (I don’t remember exactly now, but there is nowhere to check). I remember exactly, 1 interface was local, i.e. I received FOS's Internet from the router, and the second one - external.
Next, we needed a list of ranges of IP addresses of this FOS with which the command was executed:
route add ip_here mask mask_here if 0x1
thus. all traffic to the specified ip went through the specified interface.
Maybe something similar can be done in win2k8
