Remote Access VPNs address the requirement of the mobile workforce to securely connect to the organization's network. Refer to the Cisco Technical Tips Conventions for more information on document conventions. If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. Note: This setup was tested on VPN Client version 4.0.3(A) but works on earlier releases back to 3.6.1 and up to the current release.

Note: This setup was tested on PIX Software Release 6.3(1) and is expected to work on all later releases. The information in this document is based on these software and hardware versions: This sample configuration assumes that the PIX is fully operational and configured with the necessary commands in order to handle traffic as per the security policy of the organization. The VPN Client supports key sizes of 128 bits and 256 bits only. The VPN Client supports AES as an encryption algorithm starting with Cisco VPN Client release 3.6.1. The PIX Firewall supports AES key sizes of 128, 192, and 256 bits. This is in addition to the Data Encryption Standard (DES) and 3DES encryption algorithms. In Cisco Secure PIX Firewall software release 6.3 and later, the new international encryption standard AES is supported for securing site-to-site and remote access VPN connections. This example uses Cisco Easy VPN to set up the secure channel and the PIX Firewall is configured as an Easy VPN server.

Steps 2 and 3 involve configuring IPSec.This sample configuration shows how to setup a remote access VPN connection from a Cisco VPN Client to a PIX Firewall, using Advanced Encryption Standard (AES) for encryption. Configure RADIUS server support (optional).Įach step itself consists of multiple steps. Enable IKE Dead Peer Detection (optional).Ħ. Enable Reverse Route Injection (RRI) for the VPN Client (optional).ĥ. Apply mode configuration and Xauth to crypto maps.Ĥ. Define group policy for mode configuration push.ģ. There are some optional features you can configure such as DPD, but they’re not required.Ĭisco has defined the following seven steps to configuring the Easy VPN Server:Ģ. Basically, you need to configure AAA and then configure IPSec. Easy VPN Server Configuration TasksĮasy VPN Server configuration uses skills and commands I’ve already covered in previous chapters. Here’s an example-VPN Client supports Diffie-Hellman groups 1, 2, and 5, but as you know, the Easy VPN Server doesn’t support DH1. This requires a little thought when configuring connections to avoid incompatibilities. In fact, it’s so supportive, it doesn’t have some of the limitations that the IOS Easy VPN Server does. The VPN 3.5 Client supports many VPN features. You can add as many connections as you want and then select one to use from the pull-down menu before connecting.
