Hello everyone.
I'm new into this linux server world, since i've only used windows so far, and after a lot of distros testing, i decided to settle for ClearOS since it seemed to me the best one, specially price wise.

This post will be a bit long, so you can understand what i'm trying to do. You can skip to the bold part if you want to however

Over where i live, we cannot get more than 1.7 Mbps (1700 Kbps) download and 500 Kbps upload, so, me and my neighbor decided to bond our connections together in a peculiar way.

Back in January, we got a computer to receive both DSL connections, connected our houses with LAN Ethernet, and used that server as a http hoster / file downloader / file hoster / backup hoster, etc. The software we have been using to join the connections is Connectify Dispatch and Hotspot, and it has been working pretty well.

But then i found untange and it's Web caching, and i was amazed during the 15 day trial how well the Web cache works. Web Sites would load blazing fast, Windows updates would download really fast once one computer downloaded them, Steam Comunity worked super fast. And then when the trial ended, i considered buying it, but i saw the price that Untangle Premium costs, and my eyes fell off.

So, i went back to connectify and kept searching for alternatives until i found ClearOS.

ClearOS's cache works even better than Untangle, it allows me to set the size per file, the max HD size it can use, and so on, it works really great. The anti virus also works much better than untangles paid one, i might consider getting the paid updates soon, supporting this project wouldn't really be a waste of money, it works great.

But now to the main issue

I see that WAN balancing works great when one of them fails, or when various PC's are using the Internet at the same time but it has one very big issue. Since both our connections are so slow, one website should use both connections to load it's content like Untangle and Connectify does, and not only one as i see happening. Connectify cleverly distributes load, so if both WANs are free at the request moment, it will use both DSL's to send requests, if my neighbor is watching a video using one full connection, it will only use 1 DSL (the free one).

ClearOS doesn't seem to do this. It will force one website to load entirely from one DSL connection, making our scheme to get over the distance from the city problem useless to some point.

I Would like to know what files should i edit in order to force request round robbin too. Meaning, when i open a website, the requests get sent to both connections, instead of just one (for example, a website with a lot of pictures will load +/- half of them from one connection and another half from the other, making it look like we have 3.4 Mbps).

Our ISP doesn't offer bandwidth bounding so, request round robbin is the best we can have to have a faster connection.

Is it possible to activate this in ClearOS somehow?

Thank you very much for your time, hope some one can give me some lights on this!
