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 crypto map?
The crypto maps must be applied to each interface through which 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.
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.

Is split tunneling a security risk?
Note: Split tunneling can pose a security risk when configured. Since VPN Clients have unsecured access to the Internet, they can be compromised by an attacker. That attacker is then able to access the corporate LAN via the IPsec tunnel. A compromise between full tunneling and split tunneling can be to allow VPN Clients local LAN access only. Refer to PIX/ASA 7.x: Allow Local LAN Access for VPN Clients Configuration Example for more information.
What is the advantage of Easy VPN?
The main advantage of Easy VPN is that IPSec policies are centrally managed on the server (Head end router providing IPSec feature) and are pushed to client devices. This policy push is known as Mode Configuration. This requires minimum configuration on the end-user side. The IPSec policies can be configured on a RADIUS server and then downloaded to an Easy VPN server, further reducing configuration required on the Easy VPN server.
What is the command ezvpn-author group radius?
In this configuration the command ‘aaa authorization network ezvpn-author group radius’ tells us that the configuration for Easy VPN group (policies) must be downloaded from a RADIUS server.
How many group policies do you need to configure a Radius server?
Let us be more specific about the requirement so that we can configure our RADIUS server. In our requirement we need to create two group policies:
What is a remote control policy?
Controlling policy for remote access through a RADIUS server is only a single example among multiple available. There is lot that can be achieved with a RADIUS server and AAA protocol. This not only helps in centralizing everything but helps you strengthen your security posture. If a policy needs to be updated, the time it takes to propagate the updated policies is greatly reduced. This could result in lowering operational costs in the long run.
Can two groups of remote users connect to the corporate network?
Now we are required to allow two sets or groups of remote users to connect to the corporate network. Each set must be assigned a different IP address. Most important, the remote users of one group should not be allowed to connect using the profile of the other group, because each group has a unique set of policies for accessing the corporate network.

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 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.
