The following example provides settings for configuring an interface for an ISP that statically assigns an IP address for a WAN uplink. The static WAN interface and ISP gateway for this example are shown in the following figure:
Before You Begin
Connect the network equipment installed by your provider to an unused port (not the management port) of your firewall.
Step 1. Add a Direct Route
Create a direct attached route entry to create the network on box level of the firewall. Be sure to create the route on the port the ISP is plugged into.
- Go to the NETWORK > IP Configuration page.
- In the Static Interface Configuration section, click Add Static Network Interface.
- From the Network Interface list, select the port the ISP is connected to.
- Enter a Name for the network interface.
- Enter the static WAN IP address, e.g., 188.8.131.52.
- Enter the Netmask of the interface, e.g., 255.255.255.0.
- From the Classification list, select Untrusted.
- Enter the Gateway address, e.g., 184.108.40.206.
- (optional) Specify a Route Metric if the multiple default routes are configured. The route with the lowest metric is preferred.
- Click Save.
Step 2. Perform a Network Activation
After you create or change basic network configurations such as routing, you must activate your new network configuration.
- Scroll to the top of the page
- Click on the link in the warning message to activate the new network configuration.
Verify the Network Configuration
After the network activation with the new static IP address you can see the entry in the table in the Static Interface Configuration section.
