NAT

Translation

A significant advantage of NAT is that you can configure it without changing hosts or routers, other than those few routers on which NAT is configured. NAT multiplexes internal network traffic and presents it to the Internet as if it is from a single source with one IP address.

To configure NAT, complete the following steps:

￿Enable NAT translation by port (following)

￿Configure the NAT local server (page 172)

￿Configure NAT TCP or UDP timeouts (page 173)

￿Configure the NAT port range (page 174)

When you have completed these four tasks, reset the IAD for the new configuration to take effect. NAT is now fully operational.

Each IAD is configured with NAT disabled. To enable NAT translation:

1.Type P on the NAT Configuration menu to display Enable/Disable NAT Translation by Port.

2.If at least one virtual circuit on the WAN exists, and the LAN port is also configured with an IP address, or more than one PVC/DLCI exists, the IAD displays the interfaces (sample following) on this IAD.

Available Interfaces:

1.G2237 xDSL

2.10/100BaseT Ethernet

0.(Abort)

3.Otherwise, the IAD displays the WAN port table and prompt:

Port VPI VCI			Encapsulation Type		PCR		Service
1	0	40	RFC	1483(LLC Encapsulation)		0	UBR
2	0	41	RFC	2364(PPPoATM-VC Muxing)		1207UBR

3 0 101 RFC 2364(PPPoATM-VC Muxing) 1207UBR

--------

Total = 2414 cps

Maximum PCR this interface can support = 1207 cps Select Port: [1-8]

Type the port number on which to enable NAT and press Enter.

4.The IAD displays the following:

NAT Translation for this port is currently DISABLED Enter E to Enable, D to Disable: e

5.Type E to enable NAT, or D to disable NAT.

6.The IAD saves the setting and displays the NAT Configuration menu.

7.Continue with other NAT configuration tasks, or press Escape to return to the Main menu.

8.Reset the IAD (page 14) when you finish configuring NAT.
