How does ISP load balancing work?I have configured ISP load balancing with a 70/30 ratio.<br/>I use the download manager ReGet to download a couple of large files. ReGet downloads each file using multiple HTTP connections (20 in my case). I expected to see those connections distributed across the two ISPs according to the ratio. But, all connections goes through ISP1.<br/>Is there a way to configure the load balancing algorithm?<hr class="sig">Hallis© 2009 Microsoft Corporation.

Or vice versa.<br/><hr class="sig">HallisWed, 01 Jul 2009 20:26:46 Z2009-07-01T20:26:46Z
