Chapter 51 Troubleshooting

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.

The interface’s IP address may have changed. To avoid this create an IP address object based on the interface. This way the ZyWALL automatically updates every rule or setting that uses the object whenever the interface’s IP address settings change. For example, if you change LAN1’s IP address, the ZyWALL automatically updates the corresponding interface-based, LAN1 subnet address object.

I cannot set up a PPP interface.

You have to set up an ISP account before you create a PPPoE or PPTP interface.

The data rates through my cellular connection are no-where near the rates I expected.

The actual cellular data rate you obtain varies depending on the cellular device you use, the signal strength to the service provider’s base station, and so on.

I created a cellular interface but cannot connect through it.

•Make sure you have a compatible 3G device installed or connected. See Chapter 52 on page 775 for details.

•Make sure you have the cellular interface enabled.

•Make sure the cellular interface has the correct user name, password, and PIN code configured with the correct casing.
