Redmine

I want to separate the Redmine server and the Development server of our application. We are currently using mercurial and sharing it internally with the hg serve command in our intranet. Now i want to lik a project to that repository which is at the other server. I tried IP + portnumber or http://IP:port.

Is redmine capable to use mercurial repos at other servers? And how do i set it up?
