How Do I Define a Default Route in ScreenOS?
Problem:
Cannot find a default gateway option in the WebUI Cannot go out to the Internet
Solution:
This article applies to ScreenOS 4.0.0 and above.
Previously, to define a default route in ScreenOS 3.0.0 and below, you would specify the default gateway on the untrust interface. However, the routing architecture has since changed with the release of ScreenOS 4.0.0. To apply a default route in ScreenOS 4.0.0 and above, you must define a 0.0.0.0/0 static route in the route table.
To define a default route in ScreenOS, perform the following steps:
Open the WebUI. For more information on accessing the WebUI, go to Accessing Your NetScreen Using the WebUI.
From the NetScreen options menu, click Network, select Routing, and click Routing Entries.
From the Routing Entries page, click New.
From the Configuration page, in the Network Address / Netmask text boxes, enter 0.0.0.0 / 0.0.0.0.
Click to select Gateway.
From the Interface drop-down menu, click to select your outbound interface.
In the Gateway IP Address text box, enter the address of your Internet router.
Click OK. Troubleshooting
