PROBLEM CORRECTIVE ACTION
The WAN IP is provided when the ISP recognizes the user as an authorized user after
verifying the MAC address, Host Name or User ID.
Find out the verification method used by your ISP.
If the ISP checks the LAN MAC Address, tell the ISP the WAN MAC address of the
ZyWALL. The WAN MAC can be obtained from menu 24.1.
In case the ISP does not allow you to use a new MAC, you can clone the MAC from the
LAN as the WAN MAC and send it to the ISP using Menu 2 - WAN Setup. It is
recommended that you configure this menu even if your ISP presently does not require
MAC address authentication.
If the ISP checks the Host Name, enter host name in the System Name field in Menu 1 -
General Setup when you connect the ZyWALL to a cable/xDSL modem.
