If you are not using RADIUS to assign IP addresses, create an IP address group (Network > Configuration > IP Address Groups) containing the pool of IP addresses that the X family device will use to allocate IP addresses to L2TP VPN clients.

Select VPN > PPTP Status. Then click the PPTP Server Configuration tab.

On the PPTP Server Configuration page, check Enable PPTP Server.

This allows VPN clients to use the device as a VPN terminator for PPTP.

Select the remote security zone on which to terminate the VPN from the PPTP security zone drop-down lists.

If you want to use Microsoft Point-to-Point Encryption, check Require encryption. This provides additional security, and is supported by Windows VPN clients.

If you are using Microsoft Networking, enter the IP addresses of your primary and secondary WINS servers in the WINS Server 1 and WINS Server 2 fields respectively.

To configure your DNS Servers, either:

•Select Device Acts as DNS Relay if you want the device to act as a proxy-DNS server (DNS relay), passing DNS queries to its configured DNS servers

•Select Specify DNS Server and enter up to two local DNS server IP addresses, in the order in which they are to be accessed, in the DNS Server fields

To assign PPTP IP Addresses, either:

•Select IP Address Assigned by RADIUS, if you want the device to use the RADIUS server to assign the PPTP client IP address.

•Select IP Address Group and select an existing group from the drop-down list, if you want the device to use an IP address group for the client.

STEP 9 Click Apply to save the changes.
