Chapter 50 Troubleshooting

Routing policies define how the ZyWALL forwards packets to their destinations. You must create a policy route for the ZyWALL to route VPN traffic through a VPN tunnel to the remote network.

The VPN wizard automatically creates a corresponding policy route. If you use the VPN > IPSec VPN or VPN > L2TP VPN screens to set up a VPN tunnel, you need to manually configure a policy route for the VPN tunnel.

I cannot download the ZyWALL’s firmware package.

The ZyWALL’s firmware package cannot go through the ZyWALL when you enable the anti- virus Destroy compressed files that could not be decompressed option. The ZyWALL classifies the firmware package as not being able to be decompressed and deletes it.

You can upload the firmware package to the ZyWALL with the option enabled, so you only need to clear the Destroy compressed files that could not be decompressed option while you download the firmware package. See Section 28.3.1 on page 408 for more on the anti- virus Destroy compressed files that could not be decompressed option.

I changed the LAN IP address and can no longer access the Internet.

If you change the IP address of your LAN interface, make sure you also change the LAN_SUBNET address object.
