- Interface Category : VPN - VPN Type : L2TP via IPSec - Give a name to your new connection 4- During this step you will need: - The public IP address of your Cisco ASA firewall and the username that were given to you by your firewall/VPN administrator. 5- Enter the password and the shared key ("Pre-shared key") your firewall/VPN administrator. Certains fournisseurs de VPN, comme TorGuard, vous permettent de changer le chiffrement utilisé, mais vous trouverez surtout L2TP/IPSec sécurisé avec AES 128-bit ou 256-bit. L2TP/IPSec est considéré comme sécurisé, mais certains experts en sécurité émettent des doutes car IPSec a été développé, en partie, par la National Security Agency américaine. Cisco IPSec utilise des algorithmes d'échange de clés puissants (jusqu'à 2048 bits) et un très bon chiffrement AES-256 bits une fois la clé de chiffrement établie. IPSec n'est pas conçu pour masquer les connexions VPN, il peut donc être sujet au filtrage de pare-feu. VPN Client est compatible avec les protocoles VPN SSL et IPSec. Pour ce dernier, il est possible de créer un tunnel VPN de type IKEv1 ou IKEV2 sur des réseaux IPv4 et IPv6. En ce qui concerne le Cisco IOS L2TP VPN 详细配置 实验背景： 在现实的网络环境中， 我们可能会遇到这样的问题：在一些较大规模的公司 中， 分公司或出差的员工需要与公司总部随时交换机密的商务信息。分公司和出 差的员工如何能成功远程访问总公司内部的资源并保证这一过程中的安全性？ 如何在局域网上实现一个 This article shows you how to configure you Cisco router to support the Cisco VPN client 32bit & 64 Bit. We show how to setup the Cisco router IOS to create Crypto IPSec tunnels, group and user authentication, plus the necessary NAT access lists to ensurn Split tunneling is properly applied so that the VPN client traffic is not NATted.

Le L2TP (Layer 2 Tunneling Protocol) permet de créer un tunnel où transitent les données. Ce protocole est breveté par Cisco. L’IPsec (Internet Protocol Security) gère toute la partie chiffrement/cryptage des communications. Le couple L2TP/IPSec est très facile à installer sur un routeur (ou NAS) comme serveur VPN.

L2TP with IPsec on the ASA allows the LNS to interoperate with native VPN clients integrated in such operating systems as Windows, MAC OS X, Android, and Cisco IOS. Only L2TP with IPsec is supported, native L2TP itself is not supported on ASA. The minimum IPsec security association lifetime supported by the Windows client is 300 seconds. If the lifetime on the ASA is set to less than 300

This address pool should not overlap with your existing network. It is 23/12/2016 Hi everyone, I have a Cisco 2801 router with IOS version 12.4(3e) and C2801-ADVIPSERVICESK9-M. I configured 2 site-to-site IPSec VPNs between the router & 2 other devices in France & Germany. Then, I configured an L2TP IPSec remote access VPN using Cisco ASA – L2TP over IPSEC VPN. Home » ASA » Cisco ASA – L2TP over IPSEC VPN. KB ID 0000571. Problem. Note: This is for Cisco ASA 5500, 5500-x, and Cisco Firepower devices running ASA Code. When Cisco released version 7 of the operating system for PIX/ASA they dropped support for the firewall acting as a PPTP VPN device. Note: If you want to use PPTP you can still terminate PPTP VPNs on 17/08/2018 Layer 2 Tunneling Protocol (L2TP) is another VPN protocol that is widely used in network World. At the beginning it has many vulnerabilities but after a while it is used with IPSec. IPSec provides extra security to L2TP. Here, the tunnel creation is done by L2TP and the encryptions is done by IPSec. Point to Pint Tunneling Protocol (PPTP) PPTP is a widely used tunnelling protocol that uses
