PPTP Settings

If you are connecting to a virtual private network (VPN), obtain the appropriate Point-to-Point Tunneling Protocol (PPTP) settings from your VPN administrator. The PPTP settings are:

Enable	Enables PPTP on your VT2142
Username	Type the user name for the PPTP connection
Password	Type the password for the PPTP connection
Server IP	Sets the IP address of the server for the VPN, in dotted-decimal format
MPPC	Enables Microsoft Point-To-Point Compression (MPPC)
MPPE	Choose one of the following for Microsoft Point-to-Point Encryption (MPPE):
	• No — MPPE is disabled (the default)
	• Required — MPPE is always enabled on your VT2142
	• Optional — If your VPN server requires MPPE, it is enabled on your VT2142; if your VPN
	server does not require MPPE. it is disabled
	If MPPE is enabled, the Strength and Stateless fields are enabled. We recommend not
	changing these settings unless directed to by Vonage or your VPN administrator.
Strength	If MPPE is enabled, sets the encryption strength on the VT2142. All three strengths — 40-bit,
	56-bit, and 128-bit (highest) — are selected by default. The most powerful encryption agreed
	on by the VPN server and the VT2142 is used.
Stateless	If selected, MPPE stateless encryption is used. If not selected, stateful encryption is used. The
	default is selected.
Authentication	You can choose:
	• Auto — The authentification method is chosen by the VPN server and the VT2142
	• CHAP — Challenge Handshake Authentication Protocol
	• PAP — Password Authentication Protocol
	• MSCHAP — Microsoft Challenge Handshake Authentication Protocol
	• MSCHAP-v2— Microsoft Challenge Handshake Authentication Protocol version 2
Debug	If selected, the PPTP client displays additional debugging information.
