Checking my connection table...











On my ASA in the office I use Cisco ASDM (Adaptive Security Device Manager) on an ASA 5500 to implement a screening policy for my office network.


An ASDM Connection table
When I check ASDM and the ASA I always look at the connection table. That tells me what traffic is being permitted through the firewall.  In the screen capture above I looked at the destination IP addresses.  Immediately one connection jumps out; 1 MB of traffic between one of my computers and a 74.125.x.x address.  It turns out I walked away from the computer while logged into a service at Google and that IP traces back to there.
