Redirect to intranet server at a specific port

Question

In my office, I've set up two servers on one Windows 7 machine (and our network is a Windows domain). One is Apache, running on port 80, and another is the built in trac server running on port 8080. I've got a DNS entry that redirects reviewboard.etc.etc to the apache server, but for the trac server it still expects the port to be specified. How can I make it so that trac.etc.etc redirects to machinename:8080?

Edit:

The solution, in case someone stumbles upon this later. The following went inside the <virtualhost *:80> block in a file included from my httpd.conf:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^trac\.etc\.etc
RewriteRule (.*) http://localhost:8080$1 [P]
ProxyPassReverse / http://localhost:8080/

Edited again to include ProxyPassReverse, without which all URLs generated by the proxied server will break

Answer 1

I don't know what "trac" is but if its default port is 8080 then set a A record for your public IP and do a NAT and Firewall through. In the more likely case its a web app/server then you still set the A record but DNS is not port aware, users will have to enter the 8080 unless you setup a redirect through Apache using something like mod redirect. - Sam's idea

Answer 2

You can always use mod_proxy to handle the redirection to another server/port seamlessly as a passthrough. The basic documentation for mod_proxy available on apache.org covers how to do this.
