RE: [FW1] Automatic NAT Sucks?



Hi Paul,

  I avoid using automatic NAT as they are more trouble than worth. I always
use
  static NAT whenever possible.

		2 reasons:
			  - more control
			  - static nat does not get allocated to all
policies unlike automatic 
                      nat, real problem if you happen to control x firewalls
which uses 
                      identical network layout's behind (ie. same internal
network ip 
                      assignment, etc.).

  You will notice that the automatic nat gets pushed to all modules whether
needed or not.
  See the category in the nat rules under the heading "Install on".

Personally, I don't like the use of automatic NAT.  Aside from the fact that
it sets up two way rules unnecessarily, does anyone have any opinions about
it.  Pros and Cons would be good.

Cheers,

Paul.
