Ok, Im new here and somewhat new to Cisco Routers. I have used them before, but not for an actual live enviornment. I happen to have the fortune of my workplace giving me a Cisco 1721 for my personal use. I have a WIC-1ENET card for internet access and a switch with about 10 pcs attached to it. I am unable to have any PC get on the internet but, can see other Computers perfectly fine. The router can ping ip addresses and websites. I am hoping that with the information below, someone can tell me where I configured it incorrectly. The ISP is a Cable internet provider and the IP address is assigned Dynamicly to me. I am not sure if the WIC-1ENET card and use cable internet, but it seems to just be a routing issue between the LAN and WAN. Thank you in advance
