ZyXEL Communications P-2302R-P1 Support Notes page 109

ZyXEL Device is attached to the cable modem directly, the ISP will reject the DHCP discovery from this MAC,
thus no IP is assigned by the ISP.
The ZyXEL Device supports to clone the MAC from the first PC the ISP installed to be its WAN MAC. To
clone the MAC from the PC you need to enter that PC's IP in menu 2. Once the MAC is received by the
ZyXEL Device, the WAN MAC in menu 24.1 will be updated and used for the ISP's authentication.
Key settings:
a. Assigned By, Choose 'IP address attached on LAN'.
b. IP Address, Enter the IP address of the PC which is installed by the ISP at the first installation.
2. Your ISP checks the 'Host Name'
Some ISPs take advantage of the 'host name' message in a DHCP packet such as @home to do the
authentication. When first installing, the ISP's tech people configure the host name as the 'Computer Name' of
the PC in the 'Networking' settings. When the ZyXEL Device is attached to the cable modem to connect to the
ISP, we should configure this host name in the ZyXEL Device's system (menu 1).
Menu 1 - General Setup
System Name= zyxel
Key Setting:

System Name= the system name must be the same as the PC's computer name.
3. Your ISP checks 'User ID'
MAC Address:
Assigned By= IP address attached on LAN
IP Address= 192.168.1.33
