Patton electronic SmartNode 4110 Series NAT/NAPT configuration task list, Creating a Napt profile

SmartWare Software Configuration Guide 11 • NAT/NAPT configuration

it should create and which IP addresses/ports it must modify (e.g. for voice connections in addition to signal- ing connections). It performs this task for the protocol FTP. Other protocols such as H.323 and SIP cannot traverse the SmartWare NAPT.

NAT/NAPT configuration task list

To configure the NAT/NAPT component, perform the tasks in the following sections:

•Creating a NAPT profile (see page 136)

•Activating NAT/NAPT (see page 136)

•Displaying NAT/NAPT configuration information (see page 139)

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.

Procedure: To create a NAPT profile and to configure the required types of NAT/NAPT

Mode: Configure

Step	Command	Purpose
1	node(cfg)#profile napt name	Creates the NAPT profile name and activates the
		basic behavior of the Dynamic NAPT
2	node(pf-napt)[name]#rangelocal-	Configures and activates the enhanced behavior of
(optional)	ip-range-start local-ip-range-stop	the Dynamic NAPT: local-ip-range-start and local-ip-
	global-ip	range-stopdefine the subset of local hosts that use
		the global NAT address global-ipto access to global
		network.
		(max. 20 entries)
		The IP ranges of different Dynamic NAPT entries must
		not overlap each other.
3	node(pf-napt)[name]#static	Creates a Static NAPT entry: local-ip/local-portis
(optional)	{ udp tcp } local-ip local-port	mapped to global-ip/global-port. If global-port is
	[global-ip][global-port]	omitted, local-portis 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)
4	node(pf-napt)[name]#rangelocal-	Configures and activates the Dynamic NAT: local-ip-
(optional)	ip-range-start local-ip-range-stop	range-start and local-ip-range-stop define the subset
	global-ip-start global-ip-stop	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.
		(max. 20 entries)
		The IP ranges of different Dynamic NAT entries must
		not overlap each other.
