DEFINITION
Enable VPN

Profile Name
A name used to identify the VPN connection.
GRE Server Address
The IP Address on which the GRE VPN server is running.
Local Tunnel Address
The Local IP address of the VPN tunnel.
Remote Tunnel Address
The Remote IP address of the other end of the VPN tunnel.
Remote Network
Enter the remote network address and subnet mask.
TTL
The Time To Live field, an 8-bit field used to remove an undeliverable data packet from a network to
avoid unnecessary network traffic across the internet. The default value of 255 is the upper limit on the
time that an IP datagram can exist. The value is reduced by at least one for each hop the data packet
takes to the next router on the route to the datagram’s destination. If the TTL field reaches zero before
the datagram arrives at its destination the data packet is discarded and an error message is sent back
to the sender.
Verbose Logging
Enable extended logging information for the VPN connection.
Reconnect Delay
The delay before attempting to reconnect to the VPN service. The Reconnect Delay must be an
integer between 30 and 65535.
Reconnect Retries
The number of times to attempt to reconnect to the VPN service. The Reconnect Retries must be a
value between 0 and 65535. A value of 0 sets the gateway to reconnect indefinitely until a connection
is made.
