IP NAT {IN | OUT}
ip nat {in|out} <nat policy-name>
DESCRIPTION
This command is entered in the Interface Configuration Mode. This command is
used to attach a NAT policy to an interface in ‘in’ or ‘out’ direction.
PARAMETERS
Note: Each interface can have only one ingress and one egress NAT policy.
EXAMPLE
In the example below, HTTP requests initiated from internal network will be
translated and sent to external network. Returning HTTP responses are
automatically allowed and translated even if there is a filter to block:
ALU(config)# match-list m1
ALU(config-match-list m1)# tcp any any service http
ALU(config)# exit
ALU(config)# ip filter f1
ALU(config-filter f1)# match m1 deny
ALU(config)# exit
ALU(config)# ip nat n1
ALU(config-nat n1)# match m1 source-nat
ALU(config)# exit
ALU(config)# interface GigabitEthernet 3/0
ALU(config-if GigabitEthernet3/0)# ip filter in f1
ALU(config-if GigabitEthernet3/0)# ip nat out n1
Parameter Description
in The keyword "in" signifies that ingress traffic is subjected to
the NAT, only if all classifiers in this NAT object are
matched.
out The keyword "out" denotes that egress traffic is subjected to
the NAT, if all classifiers in this NAT object are matched.
