Parameters
acl-number: ACL number in the range of 2000 to 3999. A packet matching a permit rule in the ACL is
translated by NAT. If you do not specify any ACL, a packet that is not sourced from the outbound
interface is translated by NAT.
address-group group-number: Specifies an address pool for NAT. The value range for the group-number
argument is 0 to 255. If no address pool is specified, the IP address of the interface is used as the
translated IP address. That is, Easy IP is enabled.
vpn-instance vpn-instance-name: Specifies the VPN to which the addresses of the address pool belong.
The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. With this option,
inter-VPN access through NAT is supported. Without this option, the addresses in the address pool do
not belong to any VPN.
no-pat: Specifies not to use the TCP/UDP port number for many-to-many NAT. If you do not specify this
keyword, the TCP/UDP port number is used for many-to-one NAT.
port-preserved: Reserves port number for many-to-one NAT.
track vrrp virtual-router-id: Associates address translation on a specific outbound interface with a VRRP
group. The virtual-router-id argument indicates the number of the VRRP group in the range of 1 to 255.
Without this argument specified, no VRRP group is associated.
