Static NAT

Hi,

I want to perform static NAT for multiple source IP address to a single IP address, how can I perform that or is that possible and what is the alternative.

Thanks in advance.

Re: Static NAT

Hi,

Which device are you using?

Are you going to NAT the internal LAN with a single Public IP to access Internet ?

Or you want to allow access from Internet to your multiple DMZ servers with a single Public ip?

Re: Static NAT

Hello,

You can use NAT overload.

Re: Static NAT

ok the config i have sent it to u achive what u want

but this will translate any connection to the 1.1.1.1 will be translated to 192.168.1.1

if u want spesific port to be translated

use the following comand which is called port forwarding

ip nat inside source static tcp 80 192.168.1.1 1.1.1.1 80

and apply this to the outside interface

ip nat outside

and this on the inside interface

ip nat inside
