PPTP Configuration

To set up the Gateway for PPTP you must allocate IP addresses from the Gateway’s LAN for use with PPTP. The connections made by PPTP will appear to come from these addresses. The addresses must be in a continuous range.

In the Address Pool for PPTP and L2TP clients field enter:

■The first LAN address you wish to reserve for PPTP clients in the First Remote IP Address field.

and

■The last LAN address you wish to reserve for PPTP clients in the Last Remote IP Address field.

If L2TP mode is selected, then the Address Pool is the same for PPTP and L2TP over IPSec clients.

These addresses must be within the Gateway’s LAN subnet and must not form part of the DHCP pool.

Click Apply to save your changes.
