I know if your firewall is a PIX it can support doing a capture from the IOS itself..
big issue (last i looked at it ) was you are limited by you buffer space..

if your firewall is plugged directly to the ISP router.. get a switch 
to interconnect them and then do a span / port mirror

IS there a step by step out there on how to setup a computer with
wireshark to be placed between a firewall and isp router?  There is a
lot of bandwidth being transmitted and need to get answers for my client
on what the traffic is.  Please advise!!

 

Thanks
