Looking for a Reverse Proxy ? Try IIS 7.5

If you need a simple but effective reverse proxy you may find IIS 7.5 suits.

Simply load up IIS 7.5, and install URL Rewrite (http://www.iis.net/downloads/microsoft/url-rewrite)

Add the URL you wish to be forwarded and enable. For example, some firewalls may not like letting port 9704 through (the OBIEE default port) so you can simply forward public traffic on the public address to 127.0.0.1:9704/analytics/saw.dll?bieehome and you are done.
