Note:
As for the ACL rule which is referenced by NAT, only the source VPN, source IP
address, and the destination IP address in it are used. They are also used to tell
whether or not two rules conflict.
Except for NAT log information, address translation is not performed for packets
generated by the switch.

Chapter 1 NAT Configuration
Remarks
Required
By configuring the
association between
ACLs and the NAT
address pool (or the
interface addresses), you
can make the NAT server
perform address
translation for packets
matching the ACL criteria
only. Before a packet from
the intranet is forwarded
to external networks, it is
first checked against the
ACLs to see if it matches
the translation criteria. If it
does, the NAT process
will find the corresponding
address pool or the
interface address by
referring to the
association, and then
translate it.
