Let’s again walk through a scenario. Suppose you’re all happy because your server is running on 192.168.0.100 and you’ve got 8080 forwarding to that local IP address.

Dynamic WAN IPs and DynDNS

Why do we need to port forward?

Because of the NAT we need to set up port forwarding to access a specific machine.
