Chapter 44 Troubleshooting
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.
I cannot set up a PPP interface, virtual Ethernet interface or virtual VLAN interface on an
Ethernet interface.
You cannot set up a PPP interface, virtual Ethernet interface or virtual VLAN interface if the
underlying interface is a member of a bridge. You also cannot add an Ethernet interface or VLAN
interface to a bridge if the member interface has a virtual interface or PPP interface on top of it.
My rules and settings that apply to a particular interface no longer work.
