PPTP 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.

This screen displays when you select

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 NBG334W 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 NBG334W

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 NBG334W 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 NBG334W.

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.

Third DNS Server

Select

From ISP

if your ISP dynamically assigns DNS server information (and

the NBG334W'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.

WAN MAC Address

The MAC address section allows users to configure the WAN port's MAC

address by either using the NBG334W’s MAC address, copying the MAC

address from a computer on your LAN or manually entering a MAC address.

Factory default

Select

Factory default

to use the factory assigned default MAC Address.

Clone the computer’s

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. Once it is

successfully configured, the address will be copied to the rom file (ZyNOS

configuration file). It will not change unless you change the setting or upload a

different ROM file.

Multicast Setup

Multicast

Select

IGMP V-1

,

IGMP V-2

or

None

. IGMP (Internet Group Multicast

Protocol) is a network-layer protocol used to establish membership in a

Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236)

is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in

wide use. If you would like to read more detailed information about

interoperability between IGMP version 2 and version 1, please see sections 4

and 5 of RFC 2236.

Windows Networking (NetBIOS over TCP/IP): NetBIOS (Network Basic Input/Output System) are TCP

or UDP broadcast packets that enable a computer to connect to and communicate with a LAN. For

some dial-up services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls. However it

may sometimes be necessary to allow NetBIOS packets to pass through to the WAN in order to find a

computer on the WAN.

Allow between LAN

and WAN

Select this check box to forward NetBIOS packets from the LAN to the WAN

and from the WAN to the LAN. If your firewall is enabled with the default

policy set to block WAN to LAN traffic, you also need to enable the default

WAN to LAN firewall rule that forwards NetBIOS traffic.

Clear this check box to block all NetBIOS packets going from the LAN to the

WAN and from the WAN to the LAN.

Allow Trigger Dial

Select this option to allow NetBIOS packets to initiate calls.
