"PPTP Client Configuration" window can let you enable the PPTP client function by checking the
"Enable" box.
PPTP Client List & Status
"PPTP Client List & Status" window shows your defined PPTP clients and their tunnel connection
status. Only some important information for all tunnels are shown in the list as following diagram.
Configuration for A PPTP Client
"Configuration for A PPTP Client" window let you specify the required parameters for a PPTP VPN
client, such as "PPTP Client Name", "Interface", "Operation Mode", "Remote IP/FQDN", "User Name",
"Password", "Default Gateway/Remote Subnet", "Authentication Protocol", "MPPE Encryption", "NAT
before Tunneling", "LCP Echo Type" and tunnel activation.
Please be noted the "Default Gateway/Remote Subnet" configuration item. There are two options,
"Default Gateway" and "Remote Subnet". When you choose "Remote Subnet", you need specify one
more setting: the remote subnet. It is for the Intranet of PPTP VPN server. So, at PPTP client peer, the
packets whose destination is in the dedicated subnet will be transferred via the PPTP VPN tunnel.
Others will be transferred based on current routing policy of the security gateway at PPTP client peer.
But, if you choose "Default Gateway" option for the PPTP client peer, all packets will be transferred via
the PPTP VPN tunnel. That means the remote PPTP VPN server gateway controls the flowing of any
packets from the PPTP client peer. Certainly, those packets come through the PPTP VPN tunnel.
Index skipping is used to reserve slots for new function insertion, when required.
