Current config
Outside x.x.x.2/27
Inside x.x.x.1/16 Private Address
DMZ x.x.x.1/16 Private Address
We are using static NAT to publish all of our servers in the DMZ this works very well no issues. We are installing a OCS 2007 Edge server and one of the requirements is to have a public routable IP on the interface that does voice and video. Entry my problem, how do I get one of my public IPs routed through our ASA 5510 to the server.

I thought about adding a sub interface on another VLAN for this and assigning one of my public IPs to the sub interface and then another to the server nic. My question is will this cause routing issues? because basicly I would have the same network assigned to 2 interfaces but my default route statments are assined by interface. Very confusing, would like some guidance on this before I jump in and make a mess of things.

You have plent of interfaces you could also use a dedicated interface or the sub interface, either wayt it works.
The only problem is you need a unique network IP block for the sub or the physical interface, it cannot not be an IP in the same network as the outside interface.

You cannot have the same network assigned to 2 different interfaces
