View Full Version : NAT terms table
04-28-2012, 09:58 AM
I am reading chapter 13 (NAT), in table 13-2 , the term ouside local is defined as name of destination host after translation , and the term outside global is defined as name of outside destination host before translation.
Can any one help in these terms? I have spent alot of time trying to get them, but still getting confused about them.

Cisco's CCNA objectives are basically these terms:
Inside local: host IP before translation
Inside global: host IP after translation
Outside local: your router interface connecting to the ISP
Outside global: The Internet destination IP address
This explains it with a diagram http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a0080094837.shtml
This get's less confusing when you consider NAT can work both ways, not just hiding your private addresses behind a public address i.e you could have a public device appear to be a local device through NAT.
