VPN

PPTP Server

The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP
uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets. Up to 25 PPTP
(Point-to-Point Tunneling Protocol) VPN tunnels can be enabled for users who are running PPTP client
software. In the Wizard, the user selects the option to create a connection to the workplace by using a VPN
connection.
To configure the PPTP Server, follow these steps.
Step 1 Click VPN > PPTP Server, and provide the following:

PPTP Server

Start and End IP Address
DNS1 and 2 IP Addresses
User Authentication
Microsoft Point-to-Point
(MPPE) Encryption
Step 2 Click Apply.

L2TP Server

Layer Two Tunneling Protocol (L2TP) is an extension of the PPTP used by an Internet service provider (ISP)
to enable VPN over the Internet. L2TP does not provide encryption for the data it tunnels. Instead, they rely
on other security protocols, such as IPsec, to encrypt their data.
The L2TP tunnel is established between the L2TP Access Concentrator (LAC) and the L2TP Network Server
(LNS). An IPsec tunnel is also established between these devices and all L2TP tunnel traffic is encrypted
using IPsec.
To configure the L2TP Server, follow these steps:
Step 1 Click VPN > L2TP Server.
Step 2 Provide the following information:

L2TP Server

Maximum Transmission
Unit
Select On or OFF to enable or disable PPTP server.
If PPTP has been enabled, enter start and end IP addresses.
Enter the IP address of the primary and secondary DNS server.
Select the user authentication (Admin or Default).
The MPPE encrypts data in PPP-based dial-up connections or PPTP VPN connections.
128-bit key MPPE encryption schemes are supported. Select the MPPE encryption
(None or 128 bits) from the drop-down list.
Check On or Off to enable or disable the L2TP server.
The size of the largest packet that can be sent over L2TP tunnel. If L2TP has been
enabled, enter the size of a packet (Range 128-1400, Default 1400).
