Setting up a NAT Rule on Nebula Gateways (Port Forwarding)

This video will explain step-by-step how to configure a NAT rule, also known as Port Forwarding, on your Zyxel NSG device.

Walkthrough Steps

By following these steps you are able to setup a port forwarding (NAT-rule) that would allow you to access services in the internal network behind the NSG from the internet:

1. Log in to nebula.zyxel.com
2. Choose the organization and site where you want to setup the NAT-rule on
3. Navigate to Gateway > Configuration > Firewall, scroll down to “NAT” and click “Add”
4. Choose the desired WAN port under “Uplink”, enter the “Public IP” of the network, a “Public port”, the “LAN IP” of the internal server and the “Local port” to which this request should be forwarded to
5. Click ”Save”

Please note: Unlike other Zyxel devices (e.g. USG series) you don´t need to create a firewall rule in Nebula, as this will be automatically done while creating the NAT rule.
