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

Select this option If your ISP did not assign you a fixed IP address. This is the

ISP

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/

Type your identification name for the PPTP server.

Select this option If your ISP did not assign you a fixed IP address. This is the

ISP

default selection.

Use Fixed IP Address

Select this option If the ISP assigned a fixed IP address.

 

 

My WAN IP

Enter your WAN IP address in this field if you selected Use Fixed IP Address.

Address

 

Remote IP Address

Enter the remote IP address (if your ISP gave you one) in this field.

 

 

Remote IP Subnet

Enter the remote IP subnet mask in this field.

Mask

 

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".
