hi,

In order the 4 entries are, Inside global - Inside local - Outside local - Outside global, please refer to the following link for more details:

http://www.cisco.com/warp/public/556/8.html

Inside local address - The IP address assigned to a host on the inside network. This is the address configured as a parameter of the computer OS or received via dynamic address allocation protocols such as DHCP. The address is likely not a legitimate IP address assigned by the Network Information Center (NIC) or service provider.

Inside global address - A legitimate IP address assigned by the NIC or service provider that represents one or more inside local IP addresses to the outside world.

Outside local address - The IP address of an outside host as it appears to the inside network. Not necessarily a legitimate address, it is allocated from an address space routable on the inside.

Outside global address - The IP address assigned to a host on the outside network by the host owner. The address is allocated from a globally routable address or network space.

HTH,

Mohammed Mahmoud.
