PROBLEM CORRECTIVE ACTION
The ISP provides the WAN IP address after authentication. Authentication may be through
the user name and password, the MAC address or the host name. Use the following
corrective actions to make sure the ISP can authenticate your connection.
You need a username and password if you’re using PPPoE or PPTP encapsulation. Make
sure that you have entered the correct Service Type, User Name and Password (the
user name and password are case sensitive). Refer to the WAN Screens chapter (web
configurator) or the Internet Access chapter (SMT).
If your ISP requires MAC address authentication, you should clone the MAC address from
your computer on the LAN as the ZyWALL’s WAN MAC address. Refer to the WAN
Screens chapter (web configurator) or the WAN and Dial Backup Setup chapter (SMT). It
is recommended that you clone your computer’s MAC address, even if your ISP presently
does not require MAC address authentication.

If your ISP requires host name authentication, configure your computer’s name as the
ZyWALL’s system name. Refer to the Wizard Setup chapter (web configurator) or the
General Setup chapter (SMT).
