•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 L2TP IP Addresses, either:

•Select IP Address Assigned by RADIUS, if you want the X family to use the RADIUS server to assign the L2TP client IP address

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

Click Apply to save the changes.

PPTP Configuration

Overview

Point-to-Point Tunnelling Protocol (PPTP) is an encrypted VPN protocol like IPSec, although not as secure as IPSec. PPTP does not support gateway to gateway connections and is only suitable for connecting remote users. A PPTP Server can terminate PPTP connections from VPN clients, such as those included with Windows 2000.

You can configure the X family to act as a PPTP Server for VPN termination that is compatible with Windows PPTP VPN clients such as Windows 98 and Windows 2000. The PPTP Server function also supports MPPE 128-bit encryption.

PPTP Status

You can view and manage PPTP connections and configuration from the PPTP Status page (VPN > PPTP Status).

The following figure shows the PPTP Status page:
