10 The TTL (Time To Live) field is 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.
11 The Verbose logging option sets the router to output detailed logs regarding the GRE tunnel in the System
Log section of the router interface.
12 The Reconnect delay is the time in seconds that the router will wait before attempting to connect to the GRE
server if the connection is broken. The minimum time to wait is 30 seconds so as to not flood the GRE server
with connection requests, while the maximum time to wait is 65335 seconds.
13 The Reconnect retries is the number of connection attempts that the router will make if the GRE connection
goes down. If set to 0, the router will retry the connection indefinitely, otherwise the maximum number of
times to retry cannot be greater than 65335.
14 Click the Save button to save the changes. The VPN will attempt to connect after your click Save. Click the
Status button at the top left of the interface to return to the status window and monitor the VPN's
connection state.
