My network version 28.1.9



So I wanted some faster internets to go along with my new server so made the most elaborate and ridiculous network I could with the parts on hand!



I have a second sb6120 for comcast and decided that I would add it to my current one for double the speeds, originally I was going to just use the multiple nics in my server to use the second modem along side my existing network however that didn't work how I wanted.

My next attempt was to use a ClearOS virtual machine and just bridge the adapters to the vm, the nic with the modem and my existing network, then connect another XP virtual machine to that with a virtual nic. This also didnt work out so well, the multi-wan in clearos didn't want to work with the direct modem bridge.

At last I arrive at my current configuration, poorly visualized by the image above. I will start from the top and work my way down.

But first I had to add another computer to my setup, so I used my old workstation, an old P4 with 2gb of ram with a couple bonus nics.

My main/first modem is connected to my dd-wrt router via gigabit from there it goes to
my main computer, a 24 port switch with various thing plugged in and my new ClearOS box
The second modem plugs directly into the ClearOS box with gigabit, the new box uses multi-wan to manage the 2 connections and then provides network access to a third nic

this nic is connected directly to my server via one out of its 2 nics, the second nic is connected back to my orginal network for file sharing and other local network apps.

In order to keep the local area network nic on my server from connection to the internet, I simply changed the dns server to the local interface creating a loopback, this allows the server to only connect to the internet by the second load balanced nic.

I get very good speeds using this config with usenet, torrenting I get good speeds but I have to work out some bugs. Here is a screenshot of newsleecher doing its thing, I am getting 9.24 megabytes p/s download

 


There is a configuration issue on the second modem that will only allow it to hit 2 MB a second with usenet, I need to talk to comcast because I think my account is on the wrong tier :/
