General>Network>NAT with PPTP Client

The SonicWALL can use Point-to-Point Tunneling Protocol over Ethernet to connect to a PPTP server. This option supports older network implementations requiring tunneling support.

Configuring NAT with PPTP Client

To configure NAT with PPTP Client, complete the following instructions.

  1. Select NAT with PPTP Client from the Network Addressing Mode menu.

  2. Enter a unique IP address from your LAN address range in the SonicWALL LAN IP Address field. The SonicWALL LAN IP Address is the address assigned to the SonicWALL LAN port and is used for management of the SonicWALL.

  3. Enter your network subnet mask in the LAN Subnet Mask field. The LAN Subnet Mask tells your SonicWALL which IP addresses are on your LAN. Use the default value, "255.255.255.0", if there are less than 254 computers on your LAN.

  4. If you obtain a WAN IP address from the PPTP server, select Obtain an IP address using DHCP. If you have WAN IP address information, select Use the specified IP address, and enter your WAN information in the WAN Gateway(Router) Address, SonicWALL WAN IP (NAT Public) Address, and WAN Subnet Mask fields.

  5. Enter the DNS server IP address in the DNS Server 1 field.

  6. Enter the PPTP server host name in the PPTP Host Name field.

  7. Enter the IP address of the PPTP server in the PPTP Server IP Address field.

  8. Enter your user name and password in the User Name and User Password fields.

  9. Select the Disconnect after __ Minutes of Inactivity check box to automatically disconnect the L2TP connection after a specified period of inactivity. Define a maximum number of minutes of inactivity in the Minutes field. This value can range from 1 to 99 minutes.

  10. Click Update. Once the SonicWALL has been updated, a message confirming the update is displayed at the bottom of the browser window. Once the network settings have been updated, the Status bar at the bottom of the browser window displays "Restart SonicWALL for changes to take effect."

Alert! When NAT is enabled, the SonicWALL LAN IP Address is used as the gateway address for computers on the LAN.

When your SonicWALL has successfully established a PPTP connection, the Network page displays the SonicWALL WAN IP settings. The WAN Gateway (Router) Address, SonicWALL WAN IP (NAT Public) Address, WAN/LAN Subnet Mask, and DNS Servers are displayed.

Alert! Enable and configure the SonicWALL DHCP server or manually configure client DNS settings to obtain DNS name resolution.

Alert! If you change the SonicWALL LAN IP Address, you must to change the Management Station IP address to be in the same subnet as the new LAN IP address.
