Verifying and Troubleshooting Concentrator Connections

This chapter will discuss how to use various VPN 3000 concentrator tools to troubleshoot VPN connection problems. In the first half of the chapter I'll discuss some of the basic tools you'll use on the concentrator and in the second half I'll take a look at using these tools to solve common connectivity problems.

I won't be able to discuss every type of problem you'll see for terminating VPN sessions on the concentrator, but I'll discuss a few of the more common ones in this chapter. In Part III, "Clients," I'll discuss more problems and how to troubleshoot these problems from both the client and the concentrator ends of the connection. In this chapter, though, I'll focus on common problems and how to use various tools on the concentrator to pinpoint the cause of these problems.
