Thanks to all that responded.
As I was trying different utilities and wasn't seeing anything on my
outside card I then decided to disconnect my gateway machine. The high traffic
continued. I called my ISP and they told me to run tcpdump and send
it to them. A few minutes later the activity was way down. Looks normal
now.

I still plan to go through all the tools and learn them, but whatever the
problem is/was it was not inside my machines/network.
