Can I configure Cisco NAT in a way that:
Inside LAN -> IP1:Dynamic Port
Inside IP2 <- IP1:Port 80
Inside IP3 <- IP1:Port 110
To explain: I have one outside IP (IP1) and need to allow all internal clients on the LAN to reach internet through this IP, Also I want to configure a web server inside my network and make a map that all requested originated from outside my LAN to My IP (IP1 and port 80 ) to go to specific internal IP (IP2), and also all requested originated from outside my LAN to My IP (IP1 and port 110) to go to another internal IP (IP3).
Is this possible and How?
Thanks

To Do this you need three routable interfaces and to configure Access lists so I would say no as your device has only two routable interfaces.

Thank for your answer, so It's true that I can't do what I need with one real IP :-(

If my device can't support this, Then what is the device that I need, also how many Public IP did I need and for what, thanks?
