First off I should mention that I'm fairly new to configuring Cisco routers. I recently setup a Cisco 851 at my small business. We use an ADSL internet connection. During setup, I had to manually enter the IP's of my ISP's (SBC) DNS servers. What happens if they change? With the less expensive Linksys products, the router automatically obtains the DNS addresses when it obtains the IP address. Can the Cisco 851 be configured to do the same?
We're a small business with only 10 employees. They all rely on me to keep the network up and running even though I'm not trully an IT guy. I'm trying to make the network as self sufficient as possible for those days that I'm out of the office. Thank you in advance!
