The Multi-Port Forward Server is an easy-to-use solution for managing network address translation (NAT) and port forwarding within your Microsoft Azure environment. It allows you to access internal services from the internet without exposing those systems directly.

This appliance is ideal for system administrators, network engineers, and software developers. It works by listening for traffic on common ports (such as 80 or 443) and redirecting it to an internal system on a specific port.

For example, if you have an MQTT server that listens on ports 1883 and 8000, but your customer's firewall only allows traffic on ports 80 and 443, the Multi-Port Forward Server can help. It will redirect inbound traffic on port 80 to your MQTT server's port 1883, and traffic on port 443 to port 8000. This way, your MQTT server remains accessible even through restrictive firewalls, without needing any changes to the server configuration.

To set up the Multi-Port Forward Server, simply edit the /etc/multiportforward/multiportforward.config file and restart the virtual machine.
