between two peer devices over another network (like the Internet).
NBG4615 User's Guide
DESCRIPTION
This value specifies the time in minutes that elapses before the NBG4615
automatically disconnects from the PPTP server.
Type the IP address of the PPTP server.
Select this option If your ISP did not assign you a fixed IP address. This is
the default selection.
Select this option If the ISP assigned a fixed IP address.
Enter your WAN IP address in this field if you selected Use Fixed IP
Address.
Your NBG4615 will automatically calculate the subnet mask based on the IP
address that you assign. Unless you are implementing subnetting, use the
subnet mask computed by the NBG4615.
Enter a Gateway IP Address (if your ISP gave you one) in this field.
Select this to get your WAN IP address from your ISP.
Select this option If the ISP assigned a fixed IP address.
Enter your WAN IP address in this field if you selected Use Fixed IP
Address.
Select From ISP if your ISP dynamically assigns DNS server information
(and the NBG4615'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.
The MAC address section allows users to configure the WAN port's MAC
address by either using the NBG4615's MAC address, copying the MAC
address from a computer on your LAN or manually entering a MAC address.
Select Factory default to use the factory assigned default MAC Address.
Select Clone the computer's MAC address - IP Address and enter the IP
address of the computer on the LAN whose MAC you are cloning.
Click Apply to save your changes back to the NBG4615.
Click Cancel to begin configuring this screen afresh.
