ISP.

Use the following corrective actions to make sure the ISP can authenticate your

 

connection.

 

You need a user name 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 Chapter 7 on page 126 or Chapter 36 on page 528.

 

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 Chapter 7 on page 126 or Chapter 34 on page 510. 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 Chapter 3 on page 80 or Chapter 33 on

 

page 504.
