We have just upgraded to a Metro Ethernet internet connection. Our ISP has loaned us a Cisco 1841 router for a month. After that we either have to buy a router or pay rental.
Now, one potential vendor has suggested that a Cisco 1811 would be the best option for us, but our ISP has supplied an 1841. After hearing what the difference is, I'm not sure what the best option would be for us. The 1811 seems a bit small for our needs, but the 1841 seems like overkill. Is there something in between the two? We will NOT be using a T1, just an ethernet connection. Also, we don't need a firewall as we have an ASA handling firewall duties.
We are doing some routing of our old T1 IP addresses over the Ethernet connection, so please keep that in mind. I know next to nothing about Cisco routers so I need an expert opinion.
