Pre-setup: Usually this is the perimeter router so allow the firewall. Optional access-list acl permit udp source wildcard destination wildcard eq isakmp access-list acl permit esp source wildcard destination wildcard access-list acl permit ahp source wildcard destination wildcard You need to enable to securityk9 technology-package Router(config)#license boot module c2900 technology-package securityk9 Router(config)#reload Task 1: Configure the ISAKMP policy for IKE Phase 1 There are seven default isakmp policies. The most secure is the default. We will configure our own. You can remember this by HAGLE. Hash, Authentication, Group (DH), Lifetime, Encryption. Router(config)#crypto isakmp policy 1 Router(config-isakmp)#hash sha Router(config-isakmp)#authentication pre-share Router(config-isakmp)#group 5 Router(config-isakmp)#lifetime 3600 Router(config-isakmp)#encryption aes 256 We used a pre-shared key for authentication so we need to specify the password for the first phase. Router(config)#crypto isakmp key derpyisbestpony address 208.77.5.1 show crypto isakmp policy Task 2: Configure the IPsec Policy for IKE Phase 2 Configure the encryption and hashing algorithms that you will use for the data sent thought the IPsec tunnel. Hence the transform. Router(config)#crypto ipsec transform-set transform_name esp-aes esp-sha-hmac Task 3: Configure ACL to define interesting traffic Even though the tunnel is setup it doesn’t exist yet. Interesting traffic must be detected before IKE Phase 1 negotiations can begin. Allow the local lan to the remote lan. Router(config)#access-list 101 permit ip 192.168.0.0 0.0.0.255 10.0.0.0 0.0.0.255 show crypto isakmp sa Task 4: Configure a Crypto Map for the IPsec Policy Now that interesting traffic is defined and an IPsec transform set is configured, you need to bind them together with a crypto map. Rotuer(config)# crypto map map_name seq_num ipsec-isakmp What traffic will be interesting? The access-list we made before. Router(config-crypto-map)#match address 101 The transform-set we created earlier for the IPsec tunnel. Router(config-crypto-map)# set transform-set transform_name The peer router you’re connecting to. Router(config-crypto-map)#set peer 172.30.2.2 You need to set the type of DH you want to use. Router(config-crypto-map)#set pfs group5 How long these setting will last before it’s renegotiated Router(config-crypto-map)#set security-association lifetime seconds 900 Task 5: Apply the IPsec Policy Apply the crypto map to the interface.

IPsec security associations
 
03:17
This tutorial explains what IPsec security associations (SAs) are. It shows that SAs store the parameters needed to encrypt and authenticate IPsec packets flowing from a sender to a receiver. Both sender and receiver use a Security Parameter Index (SPI) to identify which parameters belong to which association. The SPI is included in each IPsec packet.

GRE over IPSec Site-to-Site VPNs w/Crypto Maps: IKEv1
 
01:12:03
In this video we take a look at the configuration and application of GRE over IPSec site-to-site tunnels between Cisco routers. Throughout this video we compare and contrast the "crypto map" approach to the "SVTI" approach and some of the background of crytpo maps. We also configure OSPF as our dynamic routing protocol of choice over our point-to-point GRE tunnel. Hope you enjoy!!!

IPsec Overview: A secure network starts with a strong security policy that defines the freedom of access to information and dictates the deployment of security in the network. Cisco Systems offers many technology solutions for building a custom security solution for Internet, extranet, intranet, and remote access networks. These scalable solutions seamlessly interoperate to deploy enterprise-wide network security. Cisco System's IPsec delivers a key technology component for providing a total security solution. Cisco's IPsec offering provides privacy, integrity, and authenticity for transmitting sensitive information over the Internet. IPsec provides secure tunnels between two peers, such as two routers. You define which packets are considered sensitive and should be sent through these secure tunnels, and you define the parameters which should be used to protect these sensitive packets, by specifying characteristics of these tunnels. Then, when the IPsec peer sees such a sensitive packet, it sets up the appropriate secure tunnel and sends the packet through the tunnel to the remote peer. More accurately, these tunnels are sets of security associations (SAs) that are established between two IPsec peers. The security associations define which protocols and algorithms should be applied to sensitive packets, and also specify the keying material to be used by the two peers. Security associations are unidirectional and are established per security protocol (AH or ESP). With IPsec you define what traffic should be protected between two IPsec peers by configuring access lists and applying these access lists to interfaces by way of crypto map sets. Therefore, traffic can be selected based on source and destination address, and optionally Layer 4 protocol, and port. The access lists used for IPsec only determine which traffic should be protected by IPsec, not which traffic should be blocked or permitted through the interface. Separate access lists define blocking and permitting at the interface. A crypto map set can contain multiple entries, each with a different access list. The crypto map entries are searched in order—the router attempts to match the packet to the access list specified in that entry. It is good practice to place the most important crypto map entries at the top of the list. When a packet matches a permit entry in a particular access list, and the corresponding crypto map entry is tagged as cisco, then CET is triggered, and connections are established if necessary. If the crypto map entry is tagged as ipsec-isakmp, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, IPsec uses the Internet Key Exchange protocol (IKE) to negotiate with the remote peer to set up the necessary IPsec security associations on behalf of the data flow. The negotiation uses information specified in the crypto map entry as well as the data flow information from the specific access list entry. If the crypto map entry is tagged as ipsec-manual, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, the traffic is dropped. In this case, the security associations are installed via the configuration, without the intervention of IKE. If the security associations did not exist, IPsec did not have all of the necessary pieces configured. Once established, the set of security associations (outbound, to the peer) is then applied to the triggering packet as well as to subsequent applicable packets as those packets exit the router. Applicable packets are packets that match the same access list criteria that the original packet matched. For example, all applicable packets could be encrypted before being forwarded to the remote peer. The corresponding inbound security associations are used when processing the incoming traffic from that peer. If IKE is used to establish the security associations, the security associations will have lifetimes set so that they periodically expire and require renegotiation, thus providing an additional level of security. Multiple IPsec tunnels can exist between two peers to secure different data streams, with each tunnel using a separate set of security associations. For example, some data streams might be just authenticated while other data streams must both be encrypted and authenticated.

With IPsec you define what traffic should be protected between two IPsec peers by configuring access lists and applying these access lists to interfaces by way of crypto map sets. Therefore, traffic can be selected based on source and destination address, and optionally Layer 4 protocol, and port. The access lists used for IPsec only determine which traffic should be protected by IPsec, not which traffic should be blocked or permitted through the interface. Separate access lists define blocking and permitting at the interface. A crypto map set can contain multiple entries, each with a different access list. The crypto map entries are searched in order—the router attempts to match the packet to the access list specified in that entry. It is good practice to place the most important crypto map entries at the top of the list. When a packet matches a permit entry in a particular access list, and the corresponding crypto map entry is tagged as cisco, then CET is triggered, and connections are established if necessary. If the crypto map entry is tagged as ipsec-isakmp, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, IPsec uses the Internet Key Exchange protocol (IKE) to negotiate with the remote peer to set up the necessary IPsec security associations on behalf of the data flow. The negotiation uses information specified in the crypto map entry as well as the data flow information from the specific access list entry. If the crypto map entry is tagged as ipsec-manual, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, the traffic is dropped. In this case, the security associations are installed via the configuration, without the intervention of IKE. If the security associations did not exist, IPsec did not have all of the necessary pieces configured. Once established, the set of security associations (outbound, to the peer) is then applied to the triggering packet as well as to subsequent applicable packets as those packets exit the router. Applicable packets are packets that match the same access list criteria that the original packet matched. For example, all applicable packets could be encrypted before being forwarded to the remote peer. The corresponding inbound security associations are used when processing the incoming traffic from that peer. If IKE is used to establish the security associations, the security associations will have lifetimes set so that they periodically expire and require renegotiation, thus providing an additional level of security. Multiple IPsec tunnels can exist between two peers to secure different data streams, with each tunnel using a separate set of security associations. For example, some data streams might be just authenticated while other data streams must both be encrypted and authenticated.
