I just had 50mb Virgin Installed and i currently have O2 ADSL+. I plan to use 02 for downloading files on my NAS and use my virgin for internet browsing / gaming on.

I would like to make it so the only computer on my network which will be using the O2 connection is my NAS (Static internal IP) and any other computers will use the Virgin 50MB connection.

Can anyone give me any advice regarding doing this, im pretty sure my draytek 2820 can handle this....

Under wan and load balance policy.
I have one pc which records weather and this up loads via ukonline. The rest of my network uses virgin cable.
