PAT (Port addressing) - Mapping private ips to one public address

[F1lby]

Hi.
Anyone know of a way to have a routers 'outside' public single ip address to present ports from different devices on the 'inside'. i.e. On the 'inside' I could have (on separate devices) a web server, an smtp server, a pop3 server, a SSH server and map 1 or more ports on each box to the single IP address on the 'outside' interface on the Cisco box. So in other words, I am working with 1 single real world IP address but wish a number of different devices to present their network services to the one address. This resolves the issue od requiring many addresses for a multi-server environment.

Many Thanks in advance

Requirement: NAT

POP
ip nat inside source static tcp 10.1.2.1 110 59.2.2.244 110 extendable
SMTP
ip nat inside source static tcp 10.1.2.1 25 59.2.2.244 25 extendable



You can also substitute the outside interface (you will need to have designated inside vs. outside NAT interfaces for this to work) assuming your on a non-static Bandwidth/Dial-on-Demain(DOD/BOD) network
