NAT pool configuration

Hi,

I am creating a NAT pool with a single start ip and end ip .. eg ip nat pool net-45-126 58.2.1.126 58.2.1.126 netmask 255.255.255.0

Is it possible ?

Hi Kaustav,

Yes that is possible for sure.

Have a look at this link for more NAT examples

http://www.cisco.com/warp/public/556/12.html#6>

Also for your requirement you can check the section

"Configuring NAT to Allow Internal Users to Access the Internet Using Overloading" in the link which I have posted above and that example is using the single start and end ip.

HTH, if yes please rate the post.

Re: NAT pool configuration

HI

If u r using a pool u need not use the overlaod.

if u r using a sigle IP for NAT u need to use the overlaod as it is called as PAT.

Thanks

Re: NAT pool configuration

hi Kas,

when ever you are having enough public ip to nat the your local lan private ip then you donot need to use the overload...but let say you are having one golbale ip and having 3 lan host with private ip then you need to have NAT with the overload keyword...which allow your multiple LAN host to connect internet with only one global ip address.

hope this will clear your idea when to use overload...

rate this post if it helps

regards

Devang
