What to do if I cannot ping any computer on the DMZ using ZyXEL Communications Gateway?
Check the 10M/100M DMZ LEDs on the front panel of your ZyXEL Communications Gateway. One of these should be lit. If both are off, check the cables between your ZyXEL Communications Gateway and the hub or station. Also, verify that the IP address and subnet mask of the ZyXEL Communications Gateway and the servers are on the same subnet.
Why can't my ZyXEL Communications Gateway get a WAN IP address from my ISP?
If you cannot get a WAN IP address from your ISP using the ZyXEL Communications Gateway, remember that the ISP provides the WAN IP address after authentication. If you're using PPPoE or PPTP, ensure you've entered the correct Service Type, User Name, and Password, noting that these are case-sensitive. If your ISP requires MAC address authentication, clone the MAC address from your computer on the LAN as the ZyWALL's WAN MAC address. If a host name is needed, configure your computer's name as the ZyWALL's system name.
What to do if no LEDs light up when I power on my ZyXEL Communications Gateway?
If none of the LEDs turn on when you turn on the ZyXEL Communications Gateway, ensure the included power adapter or cord is correctly connected to both the ZyWALL and a working power source. If the issue remains, it may indicate a hardware problem, and you should contact your vendor.
How to troubleshoot console port access on a ZyXEL Communications Gateway?
If you cannot access the ZyXEL Communications Gateway via the console port, first check that the ZyWALL is properly connected to your computer's console port. Then, verify that your communications program is configured correctly. It should use VT100 terminal emulation, with the default speed at 9600 bps (try other speeds if it has been changed), no parity, 8 data bits, 1 stop bit, and no data flow control.
What to do if I cannot ping any computer on the LAN through my ZyXEL Communications Gateway?
If you cannot ping any computer on the LAN using your ZyXEL Communications Gateway, check the 10M/100M LAN LEDs on the front panel; one of them should be lit. If both are off, inspect the cables connecting your ZyWALL to the hub or the station. Also, ensure that the IP address and subnet mask of both the ZyWALL and the computers are on the same subnet.
Why can't I access servers on the DMZ from the LAN using my ZyXEL Communications Gateway?
If you're unable to access servers on the DMZ from the LAN via your ZyXEL Communications Gateway, verify the Ethernet cable type and connections, referring to the Quick Start Guide for DMZ connection instructions. Ensure that the Ethernet adapters on both the LAN computer and the DMZ server are correctly installed and functioning. Confirm that the IP address of the DMZ port and the LAN port are on separate subnets, and ensure that NAT is properly configured for your DMZ servers.
How to get WAN IP address from ISP on ZyXEL Communications Gateway?
The ISP provides the WAN IP address after authentication, which may be through a username and password, MAC address, or hostname. If using PPPoE or PPTP, ensure you have entered the correct Service Type, User Name, and Password, paying attention to case sensitivity. If your ISP requires MAC address authentication, clone your computer's MAC address from the LAN as the ZyXEL Communications Gateway's WAN MAC address. If hostname authentication is needed, configure your computer's name as the ZyXEL Communications Gateway's system name.
