Hi, we setup a Cisco 1721 to work with Comcast cable (DHCP address from ISP) in a small SOHO environment. All the clients/host on the LAN are getting an IP address and can ping the gateway but we cannot get to the outside world (Internet). Your help is greatly appreciated as well as all suggestions for performance/security improvements. Non working config is attached due to posting space.
Thanks in advance for your help.
