Hi all!

Is there a way to configure a Cisco 827 adsl router to forward
connections (tcp and udp) coming from the internet (on a port eg port
80) to a specific host on local network?   
The actual configuration of the router can be found on the end of this
mail... what should be changed or added to enable such a port forwarding
behaviour?


thanks a lot for your help
Andreas
