Unnumbered Mode/VIP Mode
If a block of public static IP addresses was purchased from the ISP, select
Unnumbered Mode by clicking in the appropriate check box. Then, enter the IP
Address and Subnet Mask in the “Gateway Address” and “Unnumbered Subnet
Mask” text boxes below the “Unnumbered IP Address.” Click Next, then click Save
and Restart to make all changes permanent.
The Unnumbered Mode feature automatically configures the appropriate IP rout-
ing for the IP Address block. The IP route will bypass NAT, enabling the public IPs
to be routed WAN-to-LAN, as well as LAN-to-WAN.
☞
Note: The IP Address information should be obtained from the
ISP when purchasing a block of public static IP address. Contact
the ISP if this information was not received.
VIP Mode This feature is used in conjunction with Unnumbered Mode. When
VIP Mode is activated, the Modem uses NAT for private IP addressing for the Local
Area Network (LAN), allowing both public IP addressing and private IP addressing to
be configured to the LAN simultaneously, while the DHCP server is reserved for private
IP addressing. All computers using public IP addresses with Unnumbered Mode must
have the public IP addresses statically assigned.
After configuring your settings, click Next, then click Save and Restart to make all
changes permanent.
