Hello I have just got a cisco router 2651xm, and it has two fast ethernet slots. I am trying to get my ISP to work with this router. How do I go about doing that. I plugged in my ISP's cable modem to interface fastethernet 0/0 and set it to dhcp, and i set fastethernet 0/1 to ip of 192.168.1.1 and I tried connecting to the net, and it still won't work. What do I do. Can you also post the commands to do it. The router has a wic t1 slot installed. Do i plug my ISPs cable modem to that, and is that interface known as serial in the list of interfaces on the cisco router. As soon as I get this router running with my isp, do i just connect the other port to the cisco switch (2950) and configure each port, and once I configure the ports, do i have to configure hosts to the same ip as the switch ports (stupid question, I am positive i configure the host ports to a different ip but within the same subnet). But most important question is how do I get my darn router to work with my isp's router.
