Can I setup a remote access IPSec VPN on the iOS?
The Cisco IOS is a very versatile platform. You can use it to setup a remote access VPN solution without the need to deploy a Cisco ASA or any other dedicated solution. Here’s how to setup a Remote Access IPsec VPN on the Cisco Router IOS platform
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.
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.

What is the difference between IPSec and VPN?
The major difference between an IPsec VPN and an SSL VPN comes down to the network layers at which encryption and authentication are performed. IPsec operates at the network layer and can be used to encrypt data being sent between any systems that can be identified by IP addresses.
How does IPSec site-to-site VPN Work?
Site-to-Site VPN provides a site-to-site IPSec connection between your on-premises network and your virtual cloud network (VCN). The IPSec protocol suite encrypts IP traffic before the packets are transferred from the source to the destination and decrypts the traffic when it arrives.
What is the difference between VPN and Remote Access?
While having some similarities, VPN and remote desktop are functionally different things. A VPN will give you access to a network while remote desktop (or RDP) will give you control of an entire computer. If you want to have full control over a local computer from a remote location, VPN won't let you achieve that.

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 the default mode of creating IPSec tunnel?
Transport mode, the default mode for IPSec, provides for end-to-end security. It can secure communications between a client and a server. When using the transport mode, only the IP payload is encrypted. AH or ESP provides protection for the IP payload.
Is SSL VPN better than IPsec?
When it comes to corporate VPNs that provide access to a company network rather than the internet, the general consensus is that IPSec is preferable for site-to-site VPNs, and SSL is better for remote access.

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 is Cisco Easy VPN?
The Cisco Easy VPN client feature eliminates much of the tedious configuration work by implementing the Cisco Unity Client protocol. This protocol allows most VPN parameters, such as internal IP addresses, internal subnet masks, DHCP server addresses, WINS server addresses, and split-tunneling flags, to be defined at a VPN server, such as a Cisco VPN 3000 series concentrator that is acting as an IPSec server.
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 remote access VPN that uses ...
What is a Cisco 870 router?
The Cisco 870 series routers support the creation of Virtual Private Networks (VPNs). Cisco routers and other broadband devices provide high-performance connections to the Internet, but many applications also require the security of VPN connections which perform a high level of authentication and which encrypt the data between two particular ...
What is crypto map?
The crypto maps must be applied to each interface through which IP Security (IPSec) traffic flows . Applying the crypto map to the physical interface instructs the router to evaluate all the traffic against the security associations database. With the default configurations, the router provides secure connectivity by encrypting the traffic sent between remote sites. However, the public interface still allows the rest of the traffic to pass and provides connectivity to the Internet.

Note The material in this chapter does not apply to Cisco 850 series routers. Cisco 850 series routers do not support Cisco Easy VPN.
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.
Does Cisco Easy VPN support multiple destinations?
Note The Cisco Easy VPN client feature supports configuration of only one destination peer. If your application requires creation of multiple VPN tunnels, you must manually configure the IPSec VPN and Network Address Translation/Peer Address Translation (NAT/PAT) parameters on both the client and the server.
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

Can you run a packet tracer from ASA?
You can run a packet-tracer from the ASA CLI to simulate VPN traffic and see where traffic may be failing. In the following command, "inside" is our local interface, 192.168.1.100 is the local IP we're testing traffic from, 12345 is the source port (it can be anything you choose), and 192.168.2.100 is the remote IP we're trying to reach. This packet-tracer will simulate ICMP traffic.
