 ==== Advanced Scenarios ====
-As we know, only one given socket (port/protocol combination) can be forwarded at any given time. For example, if port 80 is already redirected to 192.168.1.10, this port is now "taken" from the router's pool and all inbound connections will be redirected to the mapped LAN IP address. However, there are two ways to allow you to multiplex connectivity on the same port.

 === Reverse Proxy ===
-In order to perform its job, a proxy must speak the protocol used by the application. For example, an HTTP proxy cannot serve SMTP.  If you needed to redirect, say,  HTTP to multiple internal hosts from the same external port, a reverse proxy is a good solution. According to HTTP v1.1, the target hostname must be included in the HTTP client request. This allows a proxy to fetch such information, and redirect it according to the requested domain. Nginx is able to perform this so-called reverse-proxy for HTTP/HTTPS.

 === Source Bound Redirection ===
-If the source IP and/or FQDN is well-known, you can create multiple port mapping references on the same port:protocol combination as long as the source is defined differently.  The following settings would work fine:
