4. Serial Port, Host, Device and User Configuration 4.10.1 Enable the PPTP VPN Server Select PPTP VPN on the Serial & Networks menu. Select the Enable check box to enable the PPTP Server. Select the Minimum Authentication Required. Access is denied to remote users attempting to connect using an authentication scheme weaker than the selected scheme. The schemes are described below, from strongest to weakest. • Encrypted Authentication (MS-CHAP v2): This is the strongest type of authentication to use and is the recommended option. • Weakly Encrypted Authentication (CHAP): This is the weakest type of encrypted password authentication to use. It is not recommended that clients connect using this as it provides very little password protection. Also, note that clients connecting using CHAP are unable to encrypt traffic. • Unencrypted Authentication (PAP): This is plain text password authentication. When using this type of authentication, the client password is transmitted unencrypted. • None. Select the Required Encryption Level. Access is denied to remote users attempting to connect not using this encryption level. Strong 40-bit or 128-bit encryption is recommended. In Local Address, enter the IP address to assign to the server's end of the VPN connection. In Remote Addresses, enter the pool of IP addresses to assign to the incoming client's VPN connections (e.g. 192.168.1.10-20). This must be a free IP address (or a range of free IP addresses), from the network (typically the LAN) that remote users are assigned while connected to the Tripp Lite console server. Enter the desired value of the Maximum Transmission Unit (MTU) for the PPTP interfaces into the MTU field (defaults to 1400). 69
