Running Debian 6, with latest patch of ISPConfig3 am currently running a two server mirror on the same private network. I am going to be adding a second connection to the internet via another provider. I will have a public IP for each of the two ISP connections. Each ISP will be on it's own Internal Network. I am wanting to have what essentially will be a hot standby web,DNS and Mail server on the second connection. I am wanting to start hosting my own DNS as I am told that I need two different servers on their own Public IPs Would I be better to build a third box and have it mirror the primary? Or is it feasible or possible to move my second box into a standby role on the alternate network. I do like the idea of having my current second box as a hot standby on the primary ISP network. If I were to get the box built to a point where you could shell in, could you complete the mirroring and ISP config setup? and how much would it cost? Which install guide to use? Thank you Dave
