 Service
Service to which will be applied to the IP filtering rule. User can select one of Telnet, SSH, NFS,
HTTP, HTTPS or each serial port
 Chain rule
Set the basic rule for the host to access the Pro Series as one of Accept, Drop or Reject.
The Pro Series provides a policy option. The policy decides how to treat a packet which isn' t
determined to be dropped or accepted by IP filtering list. For example, in case there is no IP filtering
list and all the services are set to be " Accept all" , the Pro Series won' t respond to any packet whose
destination port is not one of the services if the policy is " DROP"or " REJECT.
The Pro Series also provides users with simple configuration way to block a specific service(s) or
serial ports from all hosts. If the user should set any service option as " Drop all"or " Reject all" , then all
access to the service from the network will be blocked.
