What is a remote access VPN?
Remote access VPNs are used by remote clients to log in to a corporate network. The example in this chapter illustrates the configuration of a remote access VPN that uses the Cisco Easy VPN and an IPSec tunnel to configure and secure the connection between the remote client and the corporate network.
How is a VPN connection created with an IPsec server?
After the IPSec server has been configured, a VPN connection can be created with minimal configuration on an IPSec client, such as a supported Cisco 870 series access router. When the IPSec client initiates the VPN tunnel connection, the IPSec server pushes the IPSec policies to the IPSec client and creates the corresponding VPN tunnel connection.
How do I configure the Cisco Easy VPN client?
The Cisco Easy VPN client feature can be configured in one of two modes—client mode or network extension mode. Client mode is the default configuration and allows only devices at the client site to access resources at the central site. Resources at the client site are unavailable to the central site.

Is Cisco AnyConnect SSL or IPsec?
Anyconnect is the replacement for the old Cisco VPN client and supports SSL and IKEv2 IPsec. When it comes to SSL, the ASA offers two SSL VPN modes: Clientless WebVPN.
What are the 3 protocols used in IPsec?
IPsec is a suite of protocols widely used to secure connections over the internet. The three main protocols comprising IPsec are: Authentication Header (AH), Encapsulating Security Payload (ESP), and Internet Key Exchange (IKE).
How IPsec VPN works step by step?
Authenticates and protects the identities of the IPSec peers. Negotiates a matching IKE SA policy between peers to protect the IKE exchange. Performs an authenticated Diffie-Hellman exchange with the end result of having matching shared secret keys. Sets up a secure tunnel to negotiate IKE phase two parameters.

What is IPsec configuration?
Internet Protocol Security (IPsec) is a set of security protocols used to transfer IP packets confidentially across the Internet. IPsec is mandatory for all IPv6 implementations and optional for IPv4.
What is Remote Access VPN Cisco?
Remote access VPNs allow users to connect to a central site through a secure connection over a TCP/IP network such as the Internet. Remote access VPNs for IPsec IKEv2. 8.4(1) Added IPsec IKEv2 support for the AnyConnect Secure Mobility Client.
What is the difference between VPN and Remote Access?
A VPN is a smaller private network that runs on top of a larger public network, while Remote Desktop is a type of software that allows users to remotely control a computer. 2. Remote Desktop allows access and control to a specific computer, while VPN only allows access to shared network resources.
How does VPN work for Remote Access?
A remote access VPN works by creating a virtual tunnel between an employee's device and the company's network. This tunnel goes through the public internet but the data sent back and forth through it is protected by encryption and security protocols to help keep it private and secure.
How does remote access VPN Work?
A remote access VPN works by creating a virtual tunnel between an employee's device and the company's network. This tunnel goes through the public internet but the data sent back and forth through it is protected by encryption and security protocols to help keep it private and secure.
What is IP security in network security?
What is IPsec? IPsec (Internet Protocol Security) is a suite of protocols that secure network communication across IP networks. It provides security services for IP network traffic such as encrypting sensitive data, authentication, protection against replay and data confidentiality.
What are the two types of VPNs?
Two types of VPNs are supported—site-to-site and remote access. Site-to-site VPNs are used to connect branch offices to corporate offices, for example. Remote access VPNs are used by remote clients to log in to a corporate network. The example in this chapter illustrates the configuration of a site-to-site VPN that uses IPSec and ...
What is a VPN client?
VPN client—Another router, which controls access to the corporate network. LAN interface—Connects to the corporate network, with inside interface address of 10.1.1.1. GRE tunnels are typically used to establish a VPN between the Cisco router and a remote device that controls access to a private network, such as a corporate network.
What is IP security in GRE?
Note When IP Security (IPSec) is used with GRE, the access list for encrypting traffic does not list the desired end network and applications, but instead refers to the permitted source and destination of the GRE tunnel in the outbound direction. All packets forwarded to the GRE tunnel are encrypted if no further access control lists (ACLs) are applied to the tunnel interface.
What routers support virtual private networks?
The Cisco 850 and Cisco 870 series routers support the creation of virtual private networks (VPNs).
Can you negotiate with a peer in a security association?
Note With manually established security associations, there is no negotiation with the peer , and both sides must specify the same transform set.
What is IPsec tunnel?
IPsec Tunnel allows you to communicate securely to the remote office over the Internet. All the traffic through the IPSec tunnel will be encrypted by the various Encryption and Hashing algorithms. You must need static routable IP addresses, to establish the IPSec connectivity. So, let’s get started!
What does NAT stand for in VPN?
Now, we need to exclude the VPN Traffic from the NAT. NAT stands for Network Address Translation which is commonly used for providing Internet Connectivity to the Internal Hosts. If NAT is not configured in your environment, you can skip this step.
What is the subnet of R1 and R2?
Here, we have two different Cisco Routers at different locations. Router R1 connected with the ISP using public IP 1.1.1.1, and the LAN subnet is 192.168.1.0/24. On the other hand, Router R2 connected with the ISP using public IP 2.2 .2.2 and the LAN subnet is 192.168.2.0 /24. You must verify the connectivity between R1 and R2.
Do you need static IP addresses for IPSec?
As earlier discussed, we must have static routable IP addresses to establish an IPSec tunnel. Along with the IP addresses, we also have to configure ISAKMP Phase 1 and ISAKMP Phase 2 ( IPSec). Also, we need to provide a Pre-Shared Key during Phase1 Configuration. So, the summary of the requirements are:
Step1. Define the authentication and authorization methods used
In this case, we’re defining a new group called VPN which will use the local database for authenticating and authorizing the user.
Step 3. Define the VPN client group profile
We are going to name the group VPNGROUP. This is the group name that will be entered in the VPN client. Enter the preshared secret here, and a POOL name, which defines what IPs that will be handed out to the VPN clients. Then assign the name of the ACL that will be used to define the encrypted traffic that will be allowed through the VPN.
Step 4. Create a the address Pool and the access-list used for traffic encryption
Setup the IP ranged to be assigned to the address pool. In this case the starting IP is 10.100.3.1 and the last IP that can be assigned is 10.100.3.254
Step 7. Lastly, assign the crypto map to the internet interface
