PPP/ PPTP Settings

The PPP/PPTP Settings page is used to establish a connection over the DSL link, or any other type of uplink, to the ISP. A connection is needed to

set up and make or receive calls through PPP over Ethernet. The connection may be configured for manual setup or always up. Once a connection

has been established between the Quadro and the provider, Quadro users will be able to make and receive calls at any time.

The PPP/PPTP Settings page offers the following components:

The

Advanced PPP Settings link refers to the same named page where certain parts of the negotiation process during connection establishment can

be adjusted. This link is not available when accessing this page through the

Internet Configuration Wizard.

The PPTP Server text fields are only enabled when Quadro is running with the PPTP interface and require the IP address of the PPTP server.

The Encryption drop down list is only enabled when Quadro is running with the PPTP interface and it is used to select the encryption for the traffic

over the PPTP interface.

Authentication Settings require the Username and Password used for the authentication on the ISP server.

Dial Behavior radio buttons enables the following selections:

• Dial Manually - if this radio button is activated, a button

will be displayed in the main management window that

serves to switch the Internet connection on/off. When

accessing the Internet, every station of the connected

LAN has to connect to Quadro first.

• Always connected - Quadro stays in the always

connected mode. This will allow always being online in

the network.

IP Address Assignment radio buttons are used to define the

IP address assignment for the PPP interface with the

following options:

• Dynamic IP Address – the IP address to the PPP

interface will be assigned dynamically by the DHCP

server.

• Fixed IP Address – the fixed user defined IP address

will be assigned to the PPP interface.

The Keep Connection alive checkbox enables keeping the

connection alive by sending control packets dedicated for the

link state verification.

Advanced PPP Settings

The Advanced PPP Settings are used to enable/disable certain parts of the negotiation process during connection establishment. These settings

are available only if Quadro has a PPPoE WAN interface.

Attention: Disabling any of the services below may cause problems when establishing a connection including the complete connection failure. The

default settings should be changed only if the ISP (Internet Service Provider) specifically requires it or if the peer system has problems with one of

the services listed below. More information about these services can be found at:

http://www.protocols.com/pbook/ppp.htm.

The Advanced PPP Settings page offers the following group of checkboxes:

Enable automatic PPP restart at checkbox is used to select the time when the PPP connection will automatically be restarted. The checkbox

selection enables LCP echo failures text field that indicates the number of the LCP echo failure packets received before the PPP connection will be

considered as dead and will be restarted.
