Chapter 51 Troubleshooting • Make sure your ZyWALL 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 ZyWALL is connected to the Internet. I configured security settings but the ZyWALL 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 ZyWALL is not applying the custom policy route I configured. The ZyWALL 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 ZyWALL is not applying the custom firewall rule I configured. The ZyWALL checks the firewall rules in the order that they are listed. So make sure that your custom firewall rule 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.
