If you are not able to get a WAN IP address from your ISP, check which authentication method your ISP uses
and configure the settings on the P-2024. The following sections describe how you can solve this problem.
1. If your ISP checks the MAC address
Some ISPs checks the user device (usually a computer) MAC address before assigning a WAN IP address. If
the MAC address matches one on the ISP＇s system, the ISP sends an IP address to the user device and allows
Internet access. However, if the user connects another computer with a different MAC address directly to the
modem, the ISP discards any DHCP discovery packets from the un-authorized MAC address and no IP address
is assigned.
You can set the P-2024 to copy the MAC address of the computer whose MAC address is authorized by the ISP.
The P-2024 will use the copied MAC address as its WAN MAC address.
In SMT menu 2, enter the computer MAC address. The P-2024 will use the copied MAC address as its WAN
MAC address and update SMT menu 24.1.
MAC Address:
Assigned By= IP address attached on LAN
IP Address= 192.168.5.33
Field settings:
a. Assigned By: Select IP address attached on LAN.
b. IP Address: Enter the IP address of the computer whose MAC address is authorized by the ISP.
2. If your ISP checks the host name
Some ISPs checks the host name information contained in the DHCP request sent by the user computer. A host
name is text that comes after the @ sign. For example, in account@home.com, the host name is "home.com＂.
If a technician from your ISP helped you set up Internet connection, he/she set the host name as the computer
name on your computer (in the Networking screen). When you connect that computer to the P-2024, you must
set the same name as the P-2024＇s system name in SMT menu 1.
