    Running Cable Broadband with a cisco 1720

    I don't think it is using any, when you use the cable connection with a off the shelf consumer level router you do not need to use any login information.

    Running Cable Broadband with a cisco 1720

    Okay so based on what you've just confirmed, shouldn't the E0 interface ben the .18 address, and the next hop for the staic route will be the .1 gateway address?

    Running Cable Broadband with a cisco 1720

    Okay so if im understanding you correctly the in the 216.36.150.0 /24 network, the gateway at the isp's end will have a ip address (obviously) but the modem as well as the ethernet interface on my router will both hav they're own ips? I thought that the modem just modulated the signal to go...

    Thats what I though, if I have my Ethernet0 interface configured with "216.36.150.18" then wouldn't the next hop be the gateway of 216.36.150.1?

    4) Get rid of the IP route to 216.36.150.0 to the Fa0 interface, as it's not right. You don't need to point your internal routes to the inside unless you have multiple subnets besides what's configured on the router. I'm sure you have just the one. " Do you mean I don't need to point external...
