Which four types of VPN are supported using Cisco ISRs and Cisco ASA appliances?

The different types of Remote Access VPNs are:
Clientless SSL VPN (WebVPN):
– Browser-based VPN that lets users establish a secure, remote-access VPN tunnel to the ASA/ISR using a web browser.
– After authentication, users access a portal page and can access specific, supported internal resources.
Client-Based SSL VPN:
– Provides full tunnel SSL VPN connection but requires a VPN client application to be installed on the remote host.
– Requires a client, such as the Cisco AnyConnect VPN client to be installed on the host.
Cisco Easy VPN (IPSec Remote Access VPN)
– Cisco Easy VPN is an IP Security (IPsec) virtual private network (VPN) solution supported by Cisco routers and security appliances.
– It greatly simplifies VPN deployment for remote offices and mobile workers.
– Cisco Easy VPN can be deployed in a Cisco IOS router or an ASA appliance.
– We need a Cisco VPN client software that can be installed on an operating system.
Also, you can deploy Site-to-Site IPSec VPN between routers, router and ASA, and between ASAs.
