Table 5 Dynamic NAT configuration items
Item Descri
p
tion
Interface Specify an interface on which dynamic NAT is to be enabled.
ACL
Specify an ACL for dynamic NAT.
You cannot associate an ACL with multiple NAT address pools, or associate an ACL
with both Easy IP and an address pool.
Address Transfer
Select an address translation mode:
PAT: Refers to NAPT. In this mode, associating an ACL with an address pool
translates both IP addresses and port numbers.
No-PAT: Refers to many-to-many NAT. In this mode, associating an ACL with an
address pool translates only IP addresses.
Easy IP: In this mode, the NAT gateway directly uses an interface’s public IP
address as the translated IP address, and uses an ACL to match IP packets.
Only one mode can be selected for an address pool.
Address Pool Index
Specify the index of a NAT address pool for dynamic NAT.
The NAT address pool must have been configured through NAT address
configuration.
If Easy IP is selected for Address Transfer, you do not need to type an address pool
index.
