Re: Sniffing A VPN Router

I may be reading this wrong, but are you attempting to examine traffic
from other computers on the LAN?  If this is the case, then like Bruno
said, you can use something like arpspoof, ettercap, or Cain&Abel to
position yourself between a target machine and the router to study
that traffic.
