The content filter category service is not working.
• Make sure your USG has the content filter category service registered and that the license is not
expired. Purchase a new license if the license is expired.
• Make sure your USG is connected to the Internet.
I configured security settings but the USG is not applying them for certain interfaces.
Many security settings are usually applied to zones. Make sure you assign the interfaces to the
appropriate zones. When you create an interface, there is no security applied on it until you assign
it to a zone.
The USG is not applying the custom policy route I configured.
The USG checks the policy routes in the order that they are listed. So make sure that your custom
policy route comes before any other routes that the traffic would also match.
The USG is not applying the custom security policy I configured.
The USG checks the security policies in the order that they are listed. So make sure that your
custom security policy comes before any other rules that the traffic would also match.
I cannot enter the interface name I want.
The format of interface names other than the Ethernet interface names is very strict. Each name
consists of 2-4 letters (interface type), followed by a number (x, limited by the maximum number
of each type of interface). For example, VLAN interfaces are vlan0, vlan1, vlan2, ...; and so on.
• The names of virtual interfaces are derived from the interfaces on which they are created. For
example, virtual interfaces created on Ethernet interface wan1 are called wan1:1, wan1:2, and
so on. Virtual interfaces created on VLAN interface vlan2 are called vlan2:1, vlan2:2, and so on.
You cannot specify the number after the colon(:) in the Web Configurator; it is a sequential
number. You can specify the number after the colon if you use the CLI to set up a virtual
interface.
I cannot set up a PPP interface, virtual Ethernet interface or virtual VLAN interface on an
Ethernet interface.
