Now that we have determined what Phase 1 and Phase 2 attributes to use, weвЂ™re ready to configure the site-to-site IPsec tunnel between ASA1 and ASA2. Table 1 Configuration Checklist: ISAKMP/Phase-1 Attributes This checklist would serve as a reference for configuration and troubleshooting. We will start with a pre-configuration checklist to make our life easier. Therefore, it is mandatory to make sure that all these parameters are identical on the two appliances we are using as IPsec peers. If any one of the attributes is misconfigured, the IPsec tunnel fails to establish. IKE involves a combination of ISAKMP/Phase 1 and IPsec/Phase 2 attributes that are negotiated between peers. IP Security (IPsec)can use Internet Key Exchange (IKE) for key management and tunnel negotiation.

Although this tutorial was tested on ASA5520, the configuration commands are exactly the same for the other ASA models with no difference.ДЇigure 2 Cisco ASA-ASA IPsec Implementation Basic IP address configuration and connectivity exists and we will build IPsec configuration on top of this.

The outside interface of ASA1 is assigned a dynamic IP address by the service provider over DHCP, while the outside interface of ASA2 is configured with a static IP address. Here we will focus on site-to-site IPsec implementation between two Cisco ASA 5520 appliances, as shown in Figure 2. Cisco ASA 5520, a member of the Cisco ASA 5500 Series, is shown in Figure 1 below.ДЇigure 1 Cisco Adaptive Security Appliance (ASA)
