Setting up the ASA to reach the internet

qt_williams — Fri, 21 Feb 2020 13:59:07 GMT

Hello Guys! This is a simple question about setting up my ASA for internet access. In can PING anything in the internet from my OUTSIDE interface and I can PING anything from my INSIDE interface on hte private side. BUT I can reach teh internet from the workstation. I thought my 'route' was clear as this is a simple config for a test scenario. Its too simple to call TAC for so I'm looking for a little assistance from the community Below is my config:

Result of the command: "sh conf"
