[c-nsp] NAT and PAT on ASA

[Ryan West]

Tony,

I agree that I chose the wrong wording here. It should have read, the ACL you're concerned with is inbound on the outside interface.  Otherwise, the configlet is fine.

I find the netmask option to be irrelevant, unless you're falling on obvious bit boundaries within the same class or doing NAT shifting.  I guess I'm a creature of habit and go with the path of least keystrokes.  When you're creating isakmp keys, do you type:

tunnel-group 169.254.50.50 type ipsec-l2l
tunnel-group 169.254.50.50 ipsec-attributes
 pre-shared-key BestPractices

or

isakmp key BestPractices address 169.254.50.50

They both produce the same results.  I guess the BU gave up on calling it a deprecated command, it hasn't seemed to complain since 7.2.

Ryan,

I would recommend completing your static with the appropriate netmask.

Also, ACLs can be applied in and out on an interface on ASA and PIX since 
7.0.
