NAT/NAPT configuration task list
To configure the NAT/NAPT component, perform the tasks in the following sections:
•
Creating a NAPT profile (see
•
Activating NAT/NAPT (see

Displaying NAT/NAPT configuration information (see
Creating a NAPT profile
A NAPT profile defines the behavior of the NAT/NAPT component, comprising all four types of NAT/NAPT
(this profile is called ‘NAPT profile’ and not ‘NAT/NAPT profile for historical reasons). Several NAPT profiles
are admissible but there is only one NAT/NAPT component.

node(cfg)#profile napt name
Creates the NAPT profile name and activates the

ip-range-start local-ip-range-stop

Configures and activates the enhanced behavior of
the Dynamic NAPT: local-ip-range-start and local-ip-
range-stop define the subset of local hosts that use
the global NAT address global-ip to access to global
network.
(max. 20 entries)
The IP ranges of different Dynamic NAPT entries must
not overlap each other.

node(pf-napt)[name]#static
{ udp | tcp } local-ip local-port
[global-ip] [global-port]
{ udp | tcp } local-ip local-port
[global-ip] [global-port]
Creates a Static NAPT entry: local-ip/local-port is
mapped to global-ip/global-port. If global-port is
omitted, local-port is used on both sides. If global-ip
is omitted, the global address is the address of the
global interface.
(max. 20 UDP and 20 TCP entries)
mapped to global-ip/global-port. If global-port is
omitted, local-port is used on both sides. If global-ip
is omitted, the global address is the address of the
global interface.

global-ip-start global-ip-stop
ip-range-start local-ip-range-stop
global-ip-start global-ip-stop
Configures and activates the Dynamic NAT: local-ip-
range-start and local-ip-range-stop define the subset
of local hosts that use an address from the global
NAT address pool to access to global network. glo-
bal-ip-start and global-ip -stop define the global NAT
address pool.

The IP ranges of different Dynamic NAT entries must
not overlap each other.
range-start and local-ip-range-stop define the subset
