How can i tell if a certain port is passing data?

[swoodsmcse]

I have a cisco 806 router and i am trying to connect to my exchange server using Outlook web access. My exchange has a private ip but i have a public ip mapped to it. I can ping it fine over the internet but i cant connect to OWA. How can i tell if my router is letting the connection to owa go through it or not.

trace route to it and determine where the problem starts! Jeter@LasVegas.com

jeter's right a traceroute will show you where you are stopping.
From the router side, if you are worried that the port
may be blocking for some reason, write an access-list,
enable logging eq owa and apply it && buffer the log,
so you can view your results.

Enable debug on NAT translation, and try to connect to Exchange using your Outlook, monitor the router and pay attention to the ports.
