LAN->LAN IP translation for Buffalo router?

Here's my scenario:

I've got a VisualSVN server on my main dev box @ home. I'm also using a Visual Studio 2010, TortoiseSVN, VisualSVN client (for source control), and Versioned 'Artifacts' (for bug tracking).

I've got my Buffalo AirStation WHR-HP-G300N router properly configured so my business partner can connect to the SVN server. I have port forwarding enabled for the internet-side IP address (like http://99.888.77.66:443) which gets forwarded to an internal IP (like 192.168.11.开发者_JS百科6). This part is working great.

The problem I'm having is with the integration piece between TortoiseSVN and my bug tracking system. I need to provide a bugtraq:url property, but I haven't been able to get relative paths to work. So I'm forced to use an absolute URL. On my end, I need to use the name of my server (for example: bugtraq:url = https://my-server/svn/bla..), but this doesn't work for my partner. He needs to specify the IP address (for example: bugtraq:url = https://999.888.77.66:443/svn/bla...)

Is there a way to configure my router such that the IP address for this parameter gets re-routed/re-mapped to "https://my-server" if the request originates from the LAN itself? My router's software supports LAN->Internet and Internet->LAN, but I don't see LAN->LAN.

no, not even sure you can do that on a real router. Have you tried editing the host file? that would probably work.
