We have an VisualSVN Server running on our development server. An external vendor needs to access / use it (primary via TortoiseSVN, sometimes by using the web interface).
Since our IT does not allow external access to internal servers, they need to use a webserver in the DMZ (Demilitarized Zone).
Is there a way to redirect the external SVN access from this DMZ-webserver to the internal development server (preferable by using IIS 7 on the DMZ server)
