Table 33 PPTP Encapsulation
LABEL DESCRIPTION
ISP Parameters for Internet Access
Encapsulation 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. The ZyXEL Device supports only one PPTP
server connection at any given time.
To configure a PPTP client, you must configure the User Name and
Password fields for a PPP connection and the PPTP parameters for a PPTP
connection.
User Name Type the user name given to you by your ISP.
Password Type the password associated with the User Name above.
Retype to Confirm Type your password again to make sure that you have entered is correctly.
Nailed-up Connection Select Nailed-Up Connection if you do not want the connection to time out.
Idle Timeout This value specifies the time in seconds that elapses before the ZyXEL Device
automatically disconnects from the PPTP server.
PPTP Configuration
Get automatically from
ISP
Select this option If your ISP did not assign you a fixed IP address. This is the
default selection.
Use Fixed IP Address Select this option If the ISP assigned a fixed IP address.
My IP Address Type the (static) IP address assigned to you by your ISP.
My IP Subnet Mask Your ZyXEL Device 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 ZyXEL Device.
Server IP Address Type the IP address of the PPTP server.
Connection ID/
Name
Type your identification name for the PPTP server.
WAN IP Address Assignment
Get automatically from
ISP
Select this option If your ISP did not assign you a fixed IP address. This is the
default selection.
Use Fixed IP Address Select this option If the ISP assigned a fixed IP address.
My WAN IP
Address
Enter your WAN IP address in this field if you selected Use Fixed IP Address.
Remote IP Address Enter the remote IP address (if your ISP gave you one) in this field.
Remote IP Subnet
Mask
Enter the remote IP subnet mask in this field.
Metric This field sets this route's priority among the routes the ZyXEL Device uses.
The metric represents the "cost of transmission". A router determines the best
route for transmission by choosing a path with the lowest "cost". RIP routing
uses hop count as the measurement of cost, with a minimum of "1" for directly
connected networks. The number must be between "1" and "15"; a number
greater than "15" means the link is down. The smaller the number, the lower
the "cost".
