Configuring a site-to-site IPsec VPN on a Palo Alto firewall involves several key steps. Here are the main points to consider:
1. Create a Tunnel Interface:
• Set up a tunnel interface and assign it to a virtual router and security zone.
2. Configure IKE Crypto Profile (Phase 1):
• Define the IKE Crypto profile, specifying the encryption and authentication algorithms.
3. Configure IKE Gateway:
• Set up the IKE gateway with the necessary parameters, including the peer IP address and authentication method.
4. Configure IPSec Crypto Profile (Phase 2):
• Define the IPSec Crypto profile, specifying the encryption and authentication algorithms for the IPSec tunnel.
5. Create IPSec Tunnel:
• Establish the IPSec tunnel, linking it to the IKE gateway and the tunnel interface.
6. Configure VPN Routing:
• Set up routing to ensure traffic is correctly directed through the VPN tunnel.
7. Create Security Policies:
• Define security policies to allow traffic between the sites over the VPN
These steps ensure a secure and functional site-to-site IPsec VPN connection. If you need detailed instructions, Palo Alto Networks provides comprehensive guides and examples.
