This chapter introduced you to SSL VPNs. As you have seen, clientless, thin client, and network client SSL VPNs don't provide a complete VPN solution, but solve specific problems related to secure connectivity. However, network client solutions come close to providing a solution like IPsec remote access solutions. SSL VPNs are great when most of a user's access to the corporate Internet is via a web browser, but when many non-web browser-based applications are being used by the user, a Layer-3 VPN implementation, like IPsec, is probably a better choice for a solution.
Next up is Part II, "Concentrators," where I show you how to use the Cisco 3000 series concentrators as VPN gateway solutions. I'll discuss how to use them for both remote access and site-to-site connectivity, and how to troubleshoot VPN connections that terminate on them.
