Hi
I do not quite understand you question but here is a link to the configuration
guide on how to configure nat. Just search for nat.
Hope that helps you.

I have a cisco 3620 in the central office.The branch office has a 1601 and is connected using a wan interface on the 3620.The branch office want to apply nat on its virtual network by making the nat configuration on the 3620 in the central office not on the 1601 in the branch office.How can I apply ip nat inside,ip nat outside and other nat commands on the central 3620 router to do this?

Although I would need more information, I think all you have to do is to apply, in the 3620, ip nat inside at your LAN interface, ip nat outside at WAN interface that connects with branch office, and add some 'ip nat outside source static' commands for the NAT translations of the IP addresses of the branch office.
Also you could do dynamic NAT.
Hope this helps

Hi
What is the reason to implement a nat? is it address overlapping?
Because there are a lot of different ways to implement a nat.
Do you have to make a 1:1 nat or can you overload it on some addresses?
As you see there are a lot of things you have to clarify first.
Anyway if you can i would implement the nat as close to the source as possible...so in my opinion you should try to implement it on the 1601....but it is also possible on the 3620 depends on what the goal is.
Still there are different ways of inplementing nat explained in the link in the posting bevor (config guide).

The reason is that the branche office is connected to another isp in the same way that I need to do so as to have both ISPs as backup.
I have done the following configuration but it didn't work
Central office(3620)
interface FastEthernet0/0
ip address 55.X.X.X 255.255.255.248
ip nat outside
interface Serial0/0
ip address 10.0.0.1 255.255.255.252
ip nat inside
ip route 212.12.237.0 255.255.255.0 10.0.0.2
ip nat pool branch 62.x.x.x 62.x.x.x netmask 255.255.255.252
ip nat inside source list 2 pool branch overload
access-list 2 permit 212.x.x.x 0.0.0.255
Branch office(1601)
interface Ethernet0
ip address 212.x.x.x 255.255.255.0
interface Serial0
ip address 10.0.0.2 255.255.255.252
ip route 0.0.0.0 0.0.0.0 10.0.0.2
I tried also to put ip nat inside on the ethernet and ip nat outside on the serial but it also didn't work.

Hello,
If u need to implement NAT for the devices inside 1601, I don't think there is any way by which you can implement NAT on your 3600. I don't understand the need to do NAt on other side of the link when you can do it on the same side.
