Bandwidth
Enter the maximum amount of traffic, in kilobits per second, the USG can receive from
the network through the interface. Allowed values are 0 - 1048576.
MTU Maximum Transmission Unit. Type the maximum size of each data packet, in bytes,
that can move through this interface. If a larger packet arrives, the USG divides it into
smaller fragments. Allowed values are 576 - 1500. Usually, this value is 1500.
Connectivity Check The USG can regularly check the connection to the gateway you specified to make sure
it is still available. You specify how often to check the connection, how long to wait for a
response before the attempt is a failure, and how many consecutive failures are
required before the USG stops routing to the gateway. The USG resumes routing to the
gateway the first time the gateway passes the connectivity check.
Enable Select this to turn on the connection check.

Check
Check Method Select the method that the gateway allows.
