[nsp] NAT translations in IOS 12.2 on pix 515

[Mussie]

While we are on the topic...

Is there way to re-order the ACLs or insert new ACLs entries? If so, is this
supported on all versions [PIX & IOS].  The only reason I leverage 'implied
deny' is so that I can tac one more entry at the bottom without having to
re-edit the entire ACL.  I do prefer using 'deny any any' at the end.
[sorry, I'm still stuck on the old versions of IOS].

Good point.

However, I do see the logic on both sides.  An explicit deny means that 
new entries are ignored.  In the context of security policies, it can be 
advantageous to force an administrator to think through the sequence of 
their access list structure.  The explicit deny forces the admin to 
write a new access list and change the reference, or delete the access 
list and re-enter it (assuming they won't lose connectivity in the middle).
