![]() You have ESP (Encapsulation Security Protocol) and AH (Authentication Header) protocol for IPSec. Select the IPsec Protocol as per your requirement. Here, you need to give a friendly name for the IPSec Crypto profile. You need to go Network > Network Profiles > IPSec Crypto > Add. Now, you need to define Phase 2 of the IPSec Tunnel. You can change it as per your requirement.ĭefining the IPSec Crypto Profile Then, define the DH Group, Encryption, and Authentication Method. Here, you need to give a friendly name for the IKE Crypto profile. ![]() You need to go Network > Network Profiles > IKE Crypto > Add. Now, you need to define Phase 1 of the IPSec Tunnel. Also, you can attach your Management Profile in Advanced Tab if you need it.ĭefining the IKE Crypto Profile Although, you do not need to provide an IPv4 or IPv6 IP address for this interface. Also, in the Security Zone field, you need to select the security zone as defined in Step 1. Select the Virtual Router, a default in my case. To define the tunnel interface, Go to Network > Interfaces > Tunnel. You need to define a separate virtual tunnel interface for IPSec Tunnel. You can provide any name at your convenience.Ĭreating a Tunnel Interface on Palo Alto Firewall Here, you need to provide the Name of the Security Zone. To configure the security zone, you need to go Network > Zones > Add. Creating a Security Zone on Palo Alto Firewallįirst, we need to create a separate security zone on Palo Alto Firewall. You need to follow the following steps to configure IPSec Tunnel’s Phase 1 and Phase 2 in Palo Alto. PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.Ħ4 bytes from 1.1.1.1: icmp_seq=1 ttl=64 time=0.177 msĦ4 bytes from 1.1.1.1: icmp_seq=2 ttl=64 time=0.157 ms Steps to configure IPSec Tunnel on Palo Alto Firewallįirst, we will configure the IPSec Tunnel on Palo Alto Firewall. Before jump into the configuration part, just check the reachability of both devices using the ping utility. IP 1.1.1.1 is configured on the Cisco ASA firewall and 2.2.2.2 is configured on the Palo Alto Firewall as shown below:Īs you noticed, the LAN subnet 192.168.1.0/24 is connected with Cisco ASA and on the other hand, the LAN subnet 192.168.2.0/24 is connected with the Palo Alto Firewall. In this example, I’m using two routable IP addresses on both Palo Alto and Cisco ASA firewalls, which are reachable from each other. So, let’s start the configuration! Scenario – IPSec Tunnel between Cisco ASA and Palo Alto FirewallĪs already discussed, you must need static routable IP on both Palo Alto and Cisco ASA firewalls. ![]() You must have a static routable IP address to configure the IPSec tunnel. You don’t need an additional license on both devices for this feature. A basic understanding of the IPSec VPN will help you to understand this article. Although, the configuration is almost the same in other PANOS versions too. In this example, I’m using PANOS 8.1.10 on the Palo Alto firewall. In this article, we will configure the IPSec Tunnel between Palo Alto and Cisco ASA Firewall. ![]()
