We have an IIS web server (Windows Server 2008 R2) on the other side of a VPN (192.168.12.1). Our Workstations do not have access to this VPN, only our main server(192.168.4.1), which is a SBS 2011 Server.
We would like our workstations to access the remote web server over our local server for just one single URL, let's say http://192.168.4.1/company1/default.aspx?param=x
should be proxied to http://192.168.12.1/company1/default.aspx?param=x
We tried this with iis redirection, but it does not seem work, because ist still seems not to have access to the VPN (originator of request is probably still the workstation).
Would there be a simple way to let our server be the originator of the page request so it will be able to access the remote web server (proxying)?
Many thanks in advance for your advice.
