I cannot use the console port to access the ZyWALL.
1Check to see if the ZyWALL is connected to your computer's console port.
2Check to see if the communications program is configured correctly. The communications software should be configured as follows:
•VT100 terminal emulation.
•9600 bps is the default speed on leaving the factory. Try other speeds in case the speed has been changed.
•No parity, 8 data bits, 1 stop bit, data flow set to none.
I cannot ping any computer on the LAN.
1Check the 10M/100M LAN LEDs on the front panel. One of these LEDs should be on. If they are both off, check the cables between your ZyWALL and hub or the station.
2Verify that the IP address and the subnet mask of the ZyWALL and the computers are on the same subnet.
I cannot access servers on the DMZ from the LAN.
1Check your Ethernet cable type and connections. Refer to the Quick Start Guide for DMZ connection instructions.
2Make sure the Ethernet adapters on the LAN computer and the DMZ server are installed and functioning properly.
3Verify that the IP address of the DMZ port and the LAN port are on separate subnets.
4Make sure that NAT is configured for your DMZ servers.
45.3Internet Access
I cannot get a WAN IP address from the ISP.
1The ISP provides the WAN IP address after authenticating you. Authentication may be through the user name and password, the MAC address or the host name.
