NBG-417N User’s Guide

Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of data 
from a remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-
based networks.

PPTP supports on-demand, multi-protocol and virtual private networking over public networks, such 
as the Internet.

Second DNS 
Server 

Select From ISP if your ISP dynamically assigns DNS server information (and the 
NBG-417N's WAN IP address). The field to the right displays the (read-only) DNS 
server IP address that the ISP assigns. 

Select User-Defined if you have the IP address of a DNS server. Enter the DNS 
server's IP address in the field to the right. If you chose User-Defined, but leave 
the IP address set to 0.0.0.0, User-Defined changes to None after you click 
Apply. If you set a second choice to User-Defined, and enter the same IP 
address, the second User-Defined changes to None after you click Apply. 

Select None if you do not want to configure DNS servers. If you do not configure 
a DNS server, you must know the IP address of a computer in order to access it.
