Nat IP Definitions

I am a little confused on the definitions of Inside Global, Outside Global and inside Local, outside local

Can anyone clear these up in laymans terms?

Thanks

    Let's supose that you Have to remote PC's PC 1 & PC 2 , separed by the Internet , in 2 remote network's.

    something like :
    PC1 -> NAT1 -- INTERNET -- <- NAT2 <- PC2

    PC1 : 192.168.1.2
    PC2 : 192.168.1.2
    NAT 1 : ( ext IP ) : 200.1.1.1
    NAT 2 : ( ext IP ) : 201.1.1.1
    NAT 1 : ( int IP ) : 192.168.1.1
    NAT 2 : ( int IP ) : 192.168.1.1

    PC 1 is in network 1 & PC 2 is in network 2.

    inside local for PC 1 ( when comunicating with PC2 ) : 192.168.1.2
    outside local for PC 1 ( when comunicating PC 2 ): 192.168.1.2 ( IP of PC2 , therey're the same.. but it's PC2 internal IP ).

    For PC2 when comumnicating with PC1 , PC 1 ip address is outdise local and it's local IP address is linside local

    For PC1 comparing with PC 2 , INSIDE global is NAT 1 ext and outside Global is NAT 2 ext and ..

    Do you get me ? icon_wink.gif
