Port Forward Server redirects inbound traffic to a custom destination port and system.
The Port Forward Server is a port and network address translation (PAT and NAT) virtual machine. When deployed into a subscription, it is typically given a public IP address and configured to listen on common TCP ports like 80 or 443. Inbound traffic can then be re-routed to other virtual machines, which may be listening on different ports.
The purpose of the Port Forward Server is that it enhances the security of services inside the subscription by allowing the private services to remain unexposed directly to the internet, thereby positioning the Port Forward Server as a bastion host. Furthermore, the Port Forward Server allows client-traffic to traverse network firewalls which may otherwise be dropping or denying any port 80 or 443 traffic.
The business audience for this appliance would be network engineers, system architects, or security teams.
Any industry could make use of the Port Forward Server, but its use-case is especially common in IoT system deployments where MQTT or MQTTS traffic needs to be masqueraded as HTTP or HTTPS traffic.
