will go through the established L2TP VPN tunnel. That means the remote L2TP VPN server controls the flow of any packets from the L2TP client peer. Authentication Protocol 1. Required setting 2. Unchecked by default Specify one ore multiple Authentication Protocol for this L2TP tunnel. Available authentication methods are PAP / CHAP / MS-CHAP / MS-CHAP v2. MPPE Encryption 1. Unchecked by default 2. Optional setting Specify whether L2TP server supports the MPPE Protocol. Click the Enable box to enable MPPE. when MPPE Encryption is enabled, the Authentication Protocol PAP / CHAP options will t be available. LCP Echo Type 1. Auto is set by default Specify the LCP Echo Type for this L2TP tunnel. Select from Auto, Userdefined, or Disable. Auto: the system sets the Interval and Max. Failure Time. User-defined: enter the Interval and Max. Failure Time. The default value for Interval is 30 seconds, and Failure Times is 6 Times. Disable: disable the LCP Echo. Value Range: 1 ~ 99999 for Interval Time, 1~999 for Failure Time. Service Port Required setting Specify the Service Port for this L2TP tunnel to use. It can be Auto, (1701) for Cisco), or User-defined. Auto: The system determines the service port. 1701 (for Cisco): The system uses port 1701 for connecting with CISCO L2TP Server. User-defined: Enter the service port. The default value is 0. Value Range: 0 ~ 65535. Tunnel Unchecked by default Check the Enable box to enable this L2TP tunnel.

EW200 Industrial Cellular Gateway 245 5.1.4 PPTP 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. It is a client-server based techlogy. There are various levels of authentication and encryption for PPTP tunneling, usually natively as standard features of the Windows PPTP stack. The security gateway can play either "PPTP Server" role or "PPTP Client" role for a PPTP VPN tunnel, or both at the same time for different tunnels. PPTP tunnel process is nearly the same as L2TP. PPTP Server: It must have a static IP or a FQDN for clients to create PPTP tunnels. It also maintains “User Account list” (user name / password) for client login authentication; There is a virtual IP pool to assign virtual IP to each connected PPTP client. PPTP Client: It can be mobile users or gateways in remote offices with dynamic IP. To set up a tunnel, add “user name”, “password” and server’s global IP. In addition, it is required to identify the operation mode for each tunnel as main connection, failover for ather tunnel, or load balance tunnel to increase overall bandwidth. Select “Default Gateway” or “Remote Subnet” for packet flow. You can also define what kind of traffic will pass through the PPTP tunnel in the “Default Gateway / Remote Subnet” parameter. EW200 Industrial Cellular Gateway 246 For the PPTP client peer, a Remote Subnet item is required. It is for the Intranet of PPTP server peer. At PPTP client peer, the packets whose destination is in the dedicated subnet will be transferred via the PPTP tunnel. Others will be transferred based on current routing policy of the gateway at PPTP client peer. But, if 0.0.0.0/0 is entered in the Remote Subnet field, it will be treated as a "Default Gateway" setting for the PPTP client peer, and all packets, including the Internet accessing of PPTP client peers, will go through the established PPTP tunnel. That means the remote PPTP server peer controls the flow of any packets from the PPTP client peer. EW200 Industrial Cellular Gateway 247 PPTP Setting Go to Security > VPN > PPTP tab. The PPTP setting allows user to create and con PPTP tunnels.
