How does the ASA assign IP addresses to remote users?
The ASA will assign IP addresses to all remote users that connect with the anyconnect VPN client. We’ll configure a pool with IP addresses for this: Remote users will get an IP address from the pool above, we’ll use IP address range 192.168.10.100 – 200.

VPN Pool
First we will configure a pool with IP addresses that we will assign to remote VPN users:
NAT Exemption
If you have NAT enabled on the ASA then we need to make sure that traffic between 192.168.1.0 /24 (the local network) and 192.168.10.0 /24 (our remote VPN users) doesn’t get translated. To accomplish this we will configure NAT excemption. The example below is for ASA version 8.3 or higher:
Group Policy
When the remote user has established the VPN, he or she will be unable to access anything on the Internet…only the remote network is reachable. For security reasons this is a good practice as it forces you to send all traffic through the ASA. If you don’t want this then you can enable split tunneling.
Username
We configured a group policy and user but we haven’t configured any IPsec settings yet. Let’s configure phase 1…
IPsec Phase 1
This is just a basic example. We will use AES for encryption, SHA for integrity, a pre-shared key and Diffie-Hellman group 2 for key exchange. The lifetime before we have to do a renegotiation is 86400 seconds. Let’s enable this IKEv1 policy on the outside interface:
IPsec Phase 2
We will configure a transform set called “MY_TRANSFORM_SET” and we use ESP with AES/SHA. The next step is to configure a crypto map, this has to be a dynamic crypto map since the remote VPN users probably are behind dynamic IP addresses and we don’t know which ones:

Introduction
This document provides a configuration example for a Cisco Adaptive Security Appliance (ASA) Version 9.3.2 and later that allows remote VPN access to use Internet Key Exchange Protocol (IKEv2) with standard Extensible Authentication Protocol (EAP) authentication.
Background Information
The native Windows IKEv2 client does not support split tunnel (there are no CONF REPLY attributes which could be accepted by the Windows 7 client), so the only possible policy with the Microsoft client is to tunnel all traffic (0/0 traffic selectors). If there is a need for a specific split tunnel policy, AnyConnect should be used.
Configure
Note: Use the Command Lookup Tool ( registered customers only) in order to obtain more information on the commands used in this section.

Multi-context is a form of virtualization that allows multiple independent copies of an application to run simultaneously on the same hardware, with each copy (or virtual device) appearing as a separate physical device to the user. This allows a single ASA to appear as multiple ASAs to multiple independent users. The ASA family has supported virtual firewalls since its initial release; however, there was no virtualization support for Remote Access in the ASA. VPN LAN2LAN (L2L) support for multi-context was added for the 9.0 release.
