I have played with MT in the past, but never to the point that I am about to. I can get what I am looking for ~$1000 as appliances all day long, but would like to use MT since it is allot more dynamic in what all we can do with it, such as QOS and BW Limiting/Shaping.
I host servers (Exchange, Web, DNS etc.) for Corp's. Currently we are working over one DSL line (static IP's) and the DNS Servers for the companies are hosted on our network. We are running out of upstream bandwidth (512K). We are able to get a Cable connection with static IP's that does 5M Down and 3M Up. What I am looking to do, is not bonding, but provide WAN Failover.
The Appliances I'm looking at, have built in DNS Servers and multiple WAN Interfaces. I set the Primary DNS Server to be on one IP from ISP1 and the secondary to be one one ip from ISP2. When ISP1 goes down the Appliance replies back to DNS inquires that come into the secondary DNS servers IP with the appropiete IP from ISP2. Vice Versa of course the same. This provides a complete up and down stream failover.
Problem is the Box must have a trigger saying if WAN1 down supply IP from WAN2 and if WAN2 down supply IP from WAN1. If all WAN's UP I'm fine with only dishing out IP's from either or. Alternativly/Ideally If all WAN's are up just round robin or load balance.
Is this doable with MT and can somebody help me doing this? I am willing to pay of course. We would setup a project on rentacoder or getafreelancer.
I hope it is clear what I am trying to do, if not please just ask.
