The PPTP Server Configuration page is used to configure the 
PPTP server settings and offers the following components: 
The  PPTP Subnet  text fields are used to enter the IP address 
range for the PPTP server and clients within the PPTP tunnel. 
The value specified for the subnet mask is fixed to 24 to restrict 
the possible number of clients for the PPTP connection. 
Please Note: 
The first address specified in the PPTP Subnet 
will be assigned to the PPTP server; others will be assigned to 
the clients. The PPTP server subnet should be different from the 
L2TP server subnet, otherwise a corresponding error message 
will appear. 
The  Authentication  manipulation  radio buttons are used to 
select the corresponding authentication protocol by which the 
client communicates with the server. The MSCHAPv2 selection 
enables  Encryption  drop down list where the encryption 
method can be selected.

Dynamic DNS Settings 
The Dynamic DNS (DynDNS) is a service that is used to map a dynamic IP address to a host name. This service is used if you are connected to the 
Internet with a dynamic IP address (and PPP, DHCP client) and want to allow access from the Internet to a device behind the firewall. For example, if 
you want to run your own WEB server. 
To enable the DynDNS service on Quadro, you first have to choose a DynDNS provider and register at their website.
