Subject: NAT and firewalls
Folks,
I need help with understanding network address translation.
I can understand that NAT allows the network administrators to create a
private addressing domain with all the internal addresses somehow being
mapped to external addresses.
This mapping between internal and external seems to take place:
* Staticly, where one internal IP address is mapped to one external
address
* Dynamicly, where all the internal IP addresses are mapped to a few
external addresses
My question is how often is the addressing done dynamicly, and if it is, how
can I have applications addressing hosts within my private addressing
domain, if the addresses are masked by NAT.
Your help would be much appreciated
Cheers
John
