PAT configuration with manual IP in Cisco 2921

[Krishna Kumar konduri]

Dear All,

I am having a public IP address and it is not configured on any of the router interface on my cisco router. I am having 3 internal networks. Is there any way to PAT all these 3 internal networks to this public IP???

Thanks in Advance..

Hi,

yes it is eg:

ip nat pool mypool 200.1.1.1 200.1.1.1  prefix-length 30

ip nat inside source list 1 pool mypool overload

access-list 1 permit 10.0.0.0 0.0.0.255

Regards.

Hi Alain,

What is Prefix-length 30 in the syntax.?

Hi,

you could also use  netmask 255.255.255.252 instead.
