I have a very basic level of understanding with Cisco products and I need help with what should be simple and even doable by me.
I have a Cisco 1811 integrated router and am simply trying to use it on my home network. I can configure the router with an enable secret password, password encryption, VTY, aux, and cons logins with no issues. The router has 2 Ethernet interfaces, 0 and 1 and 8 switch ports.
The idea is to bring Comcast ISP service into one of the Ethernet ports and then have three machines on the switch ports able to access the Internet. Also I have an off-the shelf wireless router that I thought I would just plug that into an available switch port and allow a wireless AP as well.
This is so simply, that I can't believe I can't figure it out, but I can't.
I set int F1 to DHCP, performed a 'no shut', and connected the ISP's router and have an up and up indication. I have setup a static network with my three machines on the switch ports and enabled all applicable ports and have up and up indications - however, no traffic flow, even amongst my static Layer 2 switched LAN - not even a 'ping'. By my understanding of Layer 2, this should work right now, whether the ISP service is working or not - WHAT AM I DOING WRONG?
The addressing scheme I have ended up on is 172.16.1.0/28
Obviously without the first hurdle cleared, of why the switched LAN doesn’t work, I haven't got any deeper. Do I need to configure NAT? I don't think I would need to in the scenario right?
All of my experience, and none at the CCNA level, has been with larger Cisco equipment. One thing I noticed on the 1811 was that when trying to create a new VLAN, it appears to work yet does not do anything and the 'sh vlans' output returns nothing, not even the VLAN1 I can see with 'sh ip int brief".
Anyway, if anyone has time to help a newbie out I would appreciate it; I’m lost.
