Configuring Twice NAT
Examples
The following example configures dynamic NAT for inside network 10.1.1.0/24 when accessing servers
on the 209.165.201.1/27 network as well as servers on the 203.0.113.0/24 network:
hostname(config)# object network INSIDE_NW
hostname(config-network-object)# subnet 10.1.1.0 255.255.255.0
hostname(config)# object network MAPPED_1
hostname(config-network-object)# range 209.165.200.225 209.165.200.254
hostname(config)# object network MAPPED_2
hostname(config-network-object)# range 209.165.202.129 209.165.200.158
hostname(config)# object network SERVERS_1
hostname(config-network-object)# subnet 209.165.201.0 255.255.255.224
hostname(config)# object network SERVERS_2
hostname(config-network-object)# subnet 203.0.113.0 255.255.255.0
hostname(config)# nat (inside,outside) source dynamic INSIDE_NW MAPPED_1 destination
static SERVERS_1 SERVERS_1
hostname(config)# nat (inside,outside) source dynamic INSIDE_NW MAPPED_2 destination
static SERVERS_2 SERVERS_2
The following example configures dynamic NAT for an IPv6 inside network 2001:DB8:AAAA::/96
when accessing servers on the IPv4 209.165.201.1/27 network as well as servers on the 203.0.113.0/24
network:
hostname(config)# object network INSIDE_NW
hostname(config-network-object)# subnet 2001:DB8:AAAA::/96
hostname(config)# object network MAPPED_1
hostname(config-network-object)# range 209.165.200.225 209.165.200.254
hostname(config)# object network MAPPED_2
hostname(config-network-object)# range 209.165.202.129 209.165.200.158
hostname(config)# object network SERVERS_1
hostname(config-network-object)# subnet 209.165.201.0 255.255.255.224
hostname(config)# object network SERVERS_2
hostname(config-network-object)# subnet 203.0.113.0 255.255.255.0
hostname(config)# nat (inside,outside) source dynamic INSIDE_NW MAPPED_1 destination
static SERVERS_1 SERVERS_1
hostname(config)# nat (inside,outside) source dynamic INSIDE_NW MAPPED_2 destination
static SERVERS_2 SERVERS_2
Configuring Dynamic PAT (Hide)
This section describes how to configure twice NAT for dynamic PAT (hide). For more information, see
the “Dynamic PAT” section on page 1-8.
