I am using a cisco 831 for my home office dsl connect to the internet. The port forwarding I am setting up on the router does not appear to be working. I have connected a PC to the service port of the 831.
Is there a command I can run thru the service port that would help me trace down my port forwarding problem? What would be neat is if the router could tell me that, yes, inbound traffic was received on port
thanks,

Steve,
"show ip nat translations"
Will give you all the NAT translations configured on the box.
Post your config if you like, might get a better idea.

hope this is readable:

the port 3008 is the one I am trying to forward. What is "outside local" and "outside global"? Is that for outbound traffic?
I want a socket program running on my godaddy hosted web site to be able to connect to a socket program on a system inside my network. The error I get is "the connected party has failed to respond"
Can I run a trace on the cisco 831 which will show me if the router is receiving any traffic on port 3008 and what it is doing with it?
thanks,
-Steve
Steve,
Does that PC(10.10.10.160) listen on port 3008???
The inside global is your external IP address. The inside local is the internal IP address to which the port is being mapped. The outside global/local is the source IP address which is connecting to your router.
NB!!!
***What is the program you want to connect TO? and what port does this use? You mentioned a web server? According to your last post the mapping is to internal port 3008 on 10.10.10.160 does that listen on TCP port 3008?***Do you have any access-lists in place that could be blocking port
3008?Maybe just post your whole config if you dont mind (remove all passwords etc) so I can have a look.
