debian router and ispconfig 3.0 same box

[thedoc351]

I currently have two linux boxes one serves as a router and the other is for ispconfig. I would like to combine the two and wondered if there was a tutorial for that. Right now I am using bind on the internet server and ispconfig 3.0 on the webserver and I know those are not compatible. Any direction toward a guide that would show me how to have them both on the same server would be appreciated. Linux distro is Debian Lenny 5.0

I am sorry I believe I posted this in the wrong section. I will repost in another thread.
