Configuring a Site-to-Site VPN

In the past few chapters, we've looked at the Cisco Adaptive Security Appliance (ASA). We took a look at both basic and advanced device configurations to ensure our appliance can be deployed in a production environment. The last chapter spoke about IPSec, its functionality, and components, but most importantly, we mentioned that IPSec is used to establish a Virtual Private Network (VPN) over an unsecured network, such as the internet. This chapter focuses on using the Cisco ASA and a Cisco IOS router to create a site-to-site VPN tunnel.

In this chapter, we will focus on the following topics:

  • Configuring a site-to-site VPN using a Cisco IOS router
  • Configuring a site-to-site VPN using a Cisco ASA
  • Verifying the VPN tunnel on both the ASA and IOS router
