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:
