I've got a OES2SP1 system that I'm currently setting up in the middle of an existing network.

Currently, we have a dedicated router system which serves as a DNS and our primary internet gateway from the ISP's modem.

The modem is configured by the ISP and we have no access to it.

What I would like to do is take the router out of the equation and make this system responsible for DNS and gateway duties (and possibly BorderManager later).

However, to do this, the server would have to be able to take an IP given to it by the modem via DHCP. Is there any way to bind a dynamic IP address?
