So, I’ve been trying to find the best way to provide some extra Internet bandwidth at work without breaking the bank. My initial thought was to double up my T, until I realized how much that would cost me per month, and I still wouldn’t come close to the speed of my home cable modem connection. So, I’ve decided to bring in a Comcast business cable modem as our primary “web” connection. We’ll maintain the T for published services, outgoing email, and redundancy. Simple, cheap, great.
With the easy part out of the way, I embarked on a quest to manage two WAN links. Our firewall/gateway is a Microsoft ISA Server, which doesn’t support multiple WAN links. The only ISA add-on that does support multiple WAN links has just been deemed end of life by EMC. Just as well, as it was $3000. So, I began looking for hardware solutions. Thus began the hard part.
