I have purchased a new Cisco 877 router to replace my old router on my existing connection. I have used Cisco CP Express to perform a basic configuration and Cisco Configuration Professional for further configuration.
The problem is that I cannot get a web page. My ISP confirms that my router is connected by I can't get a webpage. I tried pinging a public server by IP address in case it was a simple DNS issue but didn't get a reply to that.
Does anybody have any idea what I have missed? I am new to Cisco routers. I am attaching a configuration file in case that sheds any light on the problem.
