I think mahesh18 is asking for how to see tcp connections going through the ASR router (to the firewall).

In that case you can try debug tcp commands.

From top of my head there should be debug tcp transations, packets and few others. You can specify source or destination IP address.

Just be careful and do NOT run debug tcp all because you may not be able to stop the debugging output from being displayed..

Other trick will be to use well known Wireshark.

I hope this will help.

If you need more info/detail please give me shout!
