If not, you need to look at the remote side config. Configure Firewall "BGP1" 2.1 Configure VPN IPSEC phase1-interface 2.2 Configure VPN IPSEC phase2-interface 1 2 3 4 5 6 7 1. Fortinet Community Knowledge Base FortiGate Technical Tip: OSPF over dial-up IPsec VPN aionescu Staff Enter the preshared key. From PC2, you should see the traffic goes through 10.2.1.1 which is the secondary tunnel interface IP set on FortiGate 1. Learn how your comment data is processed. Edit the secondary tunnel interface and create IP addresses. 2. The other VPN is added in the section Configuration overview on page 197. When configuring FortiGate_2 for OSPF, the loopback interface is created, and then you configure OSPF area networks and interfaces. Configure hub FortiGate's WAN, internal interface, and static route. Michael Pruett, CISSP has a wide range of cyber-security and network engineering expertise. Edit the primary tunnel interface and create IP addresses. Configuring security policies on FortiGate 2. When I configure OSPF it also works fine with only one branch. OSPF must be used between the hub and spoke FortiGates. 3. 1. To configure ADVPN with OSPF as the routing protocol using the CLI: Configure hub FortiGate's WAN, internal interface, and static route. I'm presenting some issues in an OSPF over IPSec configuration. get router info routing-table allget router info routing-table details x.x.x.x <-- ip you are trying to reach. The configuration is the same as in Configuring the IPsec VPN on page 198, but the interface and addresses will be different. 3. 06:05 PM. Edit the primary tunnel interface and create IP addresses.

Define the two tunnel-end addresses. 05-08-2023 When adding the second tunnel to the OSPF network, choose another unused subnet for the tunnel ends, 10.1.2.1 and 10.1.2.2 for example. The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges.. You won't see hits on the return policy if all traffic is generated from your side. However, keep in mind that VXLAN encapsulates layer 2 traffic over layer 3 networks, so the OSPF adjacency will need to be established over the VXLAN tunnel interface rather than the physical interface. This is my first post here, so I hope to get a genuine solution here. 4. 8. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Each FortiGate has two WAN interfaces connected to different ISPs. So for example, I'm looking to have 2 tunnels from branch FGT to HQ DC 1 and other to HQ DC2 and set preference for HQ DC1 tunnel. Creating redundant IPsec tunnels for FortiGate 2. From PC2, you should see the traffic goes through 10.2.1.1 which is the secondary tunnel interface IP set on FortiGate 1. 2.
