before the attempt is a failure, and how many consecutive failures are
required before the ZyWALL stops routing to the gateway. The
ZyWALL resumes routing to the gateway the first time the gateway
passes the connectivity check.
Select this to turn on the connection check.
Select the method that the gateway allows.
Select icmp to have the ZyWALL regularly ping the gateway you
specify to make sure it is still available.
Select tcp to have the ZyWALL regularly perform a TCP handshake
with the gateway you specify to make sure it is still available.
