Pound - Reverse Proxy Server

Pound is a reverse-proxy load balancing server. It accepts requests from HTTP / HTTPS clients and distributes them to one or more Web servers. The HTTPS requests are decrypted and passed to the back-ends as plain HTTP. The Pound Reverse Proxy server will allow an administrator to run two or more Web Servers behind one Router, with one static WAN IP, for delivering all of the different Websites that are Hosted on the servers behind the Router.
