What is Cisco remote access VPN?
This allows remote users to connect to the ASA and access the remote network through an IPsec encrypted tunnel. The remote user requires the Cisco VPN client software on his/her computer, once the connection is established the user will receive a private IP address from the ASA and has access to the network.
What is 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.

What are the benefits of IPsec?
IPsec provides the following security services for traffic at the IP layer: Data origin authentication—identifying who sent the data. Confidentiality (encryption)—ensuring that the data has not been read en route. Connectionless integrity—ensuring the data has not been changed en route.
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).
Which is better IPsec or OpenVPN?
In site-to-site connections, OpenVPN functions faster and provides more security than IPsec. IPsec encryption operates on a kernel level, whereas OpenVPN functions in user space. Therefore, in terms of endpoint performance, IPsec is more favorable. With OpenVPN, you're limited to the capacity of the software.
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

How does IPSec work?
In IPSec tunnel mode, the entire original IP datagram is encrypted, and it becomes the payload in a new IP packet. This mode allows a network device, such as a router, to act as an IPSec proxy. That is, the router performs encryption on behalf of the hosts. The source router encrypts packets and forwards them along the IPSec tunnel. The destination router decrypts the original IP datagram and forwards it on to the destination system. Tunnel mode protects against traffic analysis; with tunnel mode, an attacker can only determine the tunnel endpoints and not the true source and destination of the packets passing through the tunnel, even if they are the same as the tunnel endpoints.
What is IPSEC security?
IPSec is a framework of open standards, developed by the Internet Engineering Task Force (IETF), that provides data confidentiality, data integrity, and data authentication between participating peers. IPSec provides these security services at the IP layer; it uses IKE to handle negotiation of protocols and algorithms based on local policy, and to generate the encryption and authentication keys to be used by IPSec. IPSec can be used to protect one or more data flows between a pair of hosts, between a pair of security Cisco 7200 series routers, or between a security Cisco 7200 series router and a host.
What is Cisco IOS firewall?
Cisco IOS software provides an extensive set of security features with which you can configure a simple or elaborate firewall, according to your particular requirements. When you configure Cisco IOS firewall features on your Cisco router, you turn your router into an effective, robust firewall.
What is the simplest way to connect to the Internet?
The simplest connectivity to the Internet is to use a single device to provide the connectivity and firewall function to the Internet. With everything being in a single device, it is easy to address translation and termination of the VPN tunnels. Complexity arises when you need to add extra Cisco 7200 series routers to the network. This normally leads people into building a network where the corporate network touches the Internet through a network called the DMZ, or demilitarized zone.
Where is NAT configured?
NAT is configured on the router at the border of a stub domain (referred to as the inside network) and a public network such as the Internet (referred to as the outside network ). NAT translates the internal local addresses to globally unique IP addresses before sending packets to the outside network.
Do IKE policies require companion configuration?
Depending on which authentication method you specify in your IKE policies, you need to complete an additional companion configuration before IKE and IPSec can successfully use the IKE policies.
Does Cisco 7200 support intrusion detection?
Note Although Cisco 7200 series routers support intrusion detection features, intrusion detection configuration procedures are not explained in this guide. For detailed information on intrusion detection, refer to the Intrusion Detection Planning Guide.
What is IPSEC VPN?
IPSec VPN is a security feature that allow you to create secure communication link (also called VPN Tunnel) between two different networks located at different sites. Cisco IOS routers can be used to setup VPN tunnel between two sites. Traffic like data, voice, video, etc. can be securely transmitted through the VPN tunnel.
How many phases are there in IPSEC?
There are two phases in IPSec configuration called Phase 1 and Phase 2. Let’s start the configuration with R1. Before you start configuring the IPSec VPN, make sure both routers can reach each other. I have already verified that both routers can ping each other so let’s start the VPN configuration. Step 1.
What is the IP address of R2?
The two sites have static public IP address as shown in the diagram. R1 is configured with 70.54.241.1/24 and R2 is configured with 199.88.212.2/24 IP address. As of now, both routers have very basic setup like, IP addresses, NAT Overload, default route, hostnames, SSH logins, etc.
