Examples: 


  "One car was parked outside of the gate." 
  "Your work volume is increased or not"
  "He was arrested"
  "She was raped"
  "After accident he was taken to hospital"
  "He was informed about this"
  “My heart was broken”


All above statements can be in the stative form if we do not mentioned the agent.
But if we use the agent i.e. By Driver, By Boss,  By Police, By  boyfriend, By  friend, By  father, By  husband respectively, then sentence become as passive voice.

My questions are 
a) How to quickly make out whether a sentence is in the passive voice or just a simple sentence (Stative)?

B) If i use had been in above sentence does it mean the same?


Question: How do you open a port on a cisco firewall?
Answer: From the "priviledged configuration" command prompt:

static (inside_interface_name,outside_interface_name) (external ip address) (internal ip address)

access-list (access list name) ("permit" or "deny") (tcp or udp) any host (external_ip) eq (port number)

access-group (access list name) in interface (outside_interface)


Simple, right?

Good old Cisco.

The "Static" command tells the pix that the internal machine is attached to the external address, so that it will route traffic accordingly.

The "access-list" command tells the pix that you're creating a new access-list, you're allowing or denying "any" external machine to talk to your new external address on (port number) using tcp or udp packets.

The access-group command associates that access-list with an interface on the pix.

Here is a link to Cisco's Pix Command Reference for Commands starting with A. You can refer to that, if you need to. There is an example command under "access-group".

To wholly open a port for any machine you should do:

access-list open_port_whatever permit tcp any any eq (port number)
access-group open_port_whatever in interface (outside)
