Configuring NAT

[utawakevou]

We have some of our sites who are interested in using NAT to be configured on some of our routers. For eg the outside IP will be 10.1.85.xxx and the inside ip will be 192.68.0.xx

We are currently employing 1601's and 1700's.

Do I need extra hardware, like two ethernet port on routers etc.

Need your help

Hi

It always depends on what you exactly want to reach with the nat.

Here is a config guide which will help you on how to configure it.

As it looks you want to translate all addresses from source 10.1.85.xx to

192.168.0.xx.

Here a little sample:

ip nat inside source static network 10.1.85.0 192.168.0.0 /24 no-alias

And then you have to decide which interface will be your inside and outside.

interface serial 0

ip nat outside

!

interface ethernet 0

ip nat inside

Here the link to the config guide:

Hope that helps
