Introduction

This document describes how to configure LAN-to-LAN PPTP VPN between UTT AC750W and UTT HiPER 510W.

Prerequisites

Requirements
Configure PPTP VPN at two different places, AC750W works as PPTP Server, 510W works as PPTP Client, after establishing successfully, users can visit each Intranet directly.
 
Components Used
UTT AC750W;     Firmware Version:AC750Wv1.7.0-141217;
UTT HiPER 510W;   Firmware Version: nv510Wv1.1.0-120926.

( Tunnel Name: Specify a unique name for the PPTP tunnel.
 Tunnel Type:
 LAN-to-LAN: It allows two LAN sites to securely connect over the Internet. In this case, either a UTT VPN gateway or compatible VPN appliance can act as a PPTP client.
 Mobile User: It allows remote individual users to securely connect over the Internet. In this case, a laptop or desktop computer will act as a PPTP client.
 User name/Password: Specify the user name and password for the PPTP client.
 Remote Subnet IP Address/ Remote Subnet Mask: Specify the IP address and subnet mask of the remote network.)
