FTP through a separate Internet connection


What I am trying to do is to have a second connection to the Internet to use for FTP file transfers.  

The main corporate router connects to the internet through a T1 connection.  This router is owned by ATT so I would rather not make configuration changes to it.

Email, internet browsing, access to corporate servers will all go through the corporate router.  Only FTP will go through the DSL connection.

Workstations from subnet 1 will need to access the DSL connection to send and receive FTP files.

What I wanted to do was to add a DSL line and a second router.  This way the FTP transfers will have more bandwidth and will not slow down the corporate network.

Tell me if this makes sense:

Because you can only have one default gateway and therefore only one internet connection per subnet you need to put the second Internet connection on a separate subnet.

Workstation 2 will be on subnet 2 (DMZ) on the DSL router.

To make a file transfer from workstations on the main LAN you could do a remote desktop connection to workstation 2 which would do the actual file transfer.

Is there a simpler or more direct way to do this?

Managing Security Policy in a Changing Environment

The enterprise network environment is evolving rapidly as companies extend their physical data centers to embrace cloud computing and software-defined networking. This new reality means that the challenge of managing the security policy is much more dynamic and complex.

you could set a SOCKS proxy up on workstation 2
then have all the ftp clients set to use that proxy.

the workstations on the main subnet will have to be able to access subnet 2

the default gateway of workstation 2 is the DSL router

If you have a layer 3 switch as your engineering switch  , you can set up policy based routing which will allow you to dynamically route FTP traffic through the ADSL subnet and everything else via your T1 connection via the switch , this will involve a bit of config work but it will also give you resiliency if you ever decide to use your DSL as backup as well.

Thanks for the comments.  I am going to look into both of these methods.  

If I may pursue this some more, your help would be greatly appreciated.  Is there a way to have workstation 1 directly use the DSL internet connection without using workstation 2?  I'm kind of stuck on the idea that I need to use workstation 2 as a proxy either with socks or remote desktop.  Could the router be configured to do this.
