PPTP The PPTP protocol is typically used for VPN connection. Use
the necessary information from your ISP to complete the PPTP
configurations:
• IP Address: Enter the IP address of the WAN port that
can be accessable from the Internet.
• Netmask: Enter the IP address of the subnet mask.
• Gateway: Enter the IP address of default gateway.
• User Name/Password: Enter the user name and
password that are required to log into the PPTP server.
• PPTP Server IP Address: Enter the IP address of the
PPTP server.
• MPPE Encryption: Microsoft Point-to-Point Encryption
(MPPE) encrypts data in PPP-based dial-up connections
or PPTP VPN connections. Check the box to enable the
MPPE encryption to provide data security for the PPTP
connection that is between the VPN client and VPN
server.
• Connect Idle Time: Choose this option to let the security
appliance disconnect from the Internet after a specified
period of inactivity (Idle Time). This choice is
recommended if your ISP fees are based on the time that
you spend online.
• Keep Live: Choose this option to keep the connection
always on, regardless of the level of activity. This choice
is recommended if you pay a flat fee for your Internet
service.
• MTU: Choose Auto to use the default MTU size, or
choose Manual if you want to specify another size.
• MTU Value: If you choose Manual, enter the custom MTU
size in bytes.
NOTE Unless a change is required by your ISP, it is recommended
that the MTU values be left as is.
