Hi,

You can use a single public IP address to forward different ports to different hosts.

But you cant ofcourse forward the same port to multiple hosts.

If you need help provide some more information what you are trying to achieve.

Hi,

Yes , you can using static nat.

ip nat source static tcp x.x.x.x 23 y.y.y.y 23

ip nat source static tcp x.x.x.x 80 y.y.y.z 80

ip nat source static tcp x.x.x.x 443 y.y.y.h 443

ip nat source static tcp x.x.x.x 22 y.y.y.u 22

Hi Prashant,

Yes, the x.x.x.x is the public and y.y.y. are the private/inside addresses.
