Item Descri
tion
Interface Specify an interface on which the NAT policy is to be enabled.
Translation Mode
Select an address translation mode:
• Interface Address—In this mode, the NAT gateway directly uses an interface's
public IP address as the translated IP address. You do not need to configure any
address pool for this mode.
• PAT—In this mode, both IP addresses and port numbers of packets are translated.
You need to configure an address pool for this mode.
• No-PAT—In this mode, only IP addresses of packets are translated. You need to
configure an address pool for this mode.
Start IP Address
End IP Address
Specify the start and the end IP addresses for the NAT address pool.
The start IP address must be lower than the end IP address. If the end IP address and
the start IP address are the same, you specify only one IP address.
IMPORTANT:
• Only one translation mode can be selected for the same address pool.
• The maximum number of IP addresses contained in an address pool depends on
the device model.
• NAT address pools used by some device models cannot be those used by other
address translation policies, IP addresses of interfaces with Easy IP enabled, or
external IP addresses of internal servers.
