How do I enable IPsec tunnel in FortiGate?
To configure the IPSec VPN tunnels on a FortiGate 60D firewall:
- Configure the VPN Parameters. Define the VPN parameters for the primary and backup VPN tunnels.
- Define the IPv4 Policies. Define the IPv4 policies to allow access to the newly configured tunnels.
- Establish the Static Routes.
- Define the Policy Routes.
What is Phase 1 and 2 in IPsec tunnel?
Phase 1 Security Associations are used to protect IKE messages that are exchanged between two IKE peers, or security endpoints. Phase 2 Security Associations are used to protect IP traffic, as specified by the security policy for a specific type of traffic, between two data endpoints.
What is IPsec virtual tunnel interface?
IP security (IPsec) virtual tunnel interfaces (VTIs) provide a routable interface type for terminating IPsec tunnels and an easy way to define protection between sites to form an overlay network.
How does IPsec tunnel mode work?
IPsec tunnel mode is used between two dedicated routers, with each router acting as one end of a virtual “tunnel” through a public network. In IPsec tunnel mode, the original IP header containing the final destination of the packet is encrypted, in addition to the packet payload.
How create VPN tunnel in FortiGate firewall?
Configure SSL VPN settings:
- Go to VPN > SSL-VPN Settings.
- For Listen on Interface(s), select wan1.
- Set Listen on Port to 10443.
- Optionally, set Restrict Access to Limit access to specific hosts, and specify the addresses of the hosts that are allowed to connect to this VPN.
- Choose a certificate for Server Certificate.
What is main mode and aggressive mode in IPsec?
In Aggressive mode, the initiator can send only one proposal. In Main mode, the initiator can send a list of proposals. In Aggressive mode, only three messages are exchanged instead of six messages as in Main mode.
What are the modes in IPsec?
The IPsec standards define two distinct modes of IPsec operation, transport mode and tunnel mode. The modes do not affect the encoding of packets. The packets are protected by AH, ESP, or both in each mode.
Is IPSec tunnel unidirectional?
Security associations (SAs): An IPsec SA is unidirectional in nature and defines how traffic for a particular traffic flow is to be protected by IPsec.
When should I use IPsec tunnel mode?
When to Use IPsec Tunnel Mode
- Tunnel mode protects internal routing information by encrypting the original packet’s IP header by creating a new IP header on top of it.
- Tunnel mode is mandatory when one of the peers is a security gateway applying IPsec on behalf of another host.
What is the difference between transport mode and tunnel mode?
In transport mode, the sending and receiving hosts establish a connection before exchanging data. In tunnel mode, a second IP packet is sent in a completely different protocol. This protects data packets from being inspected or modified in transit.
What is difference between tunnel mode and transport mode in IPsec?
What is The Difference Between IPsec Tunnel and Transport Mode? IPsec tunnel mode sets up a secure connection, while IPsec Transport Mode only encrypts the data being sent without establishing a secure connection. In transport mode, the sending and receiving hosts establish a connection before exchanging data.
What are the types of VPN Tunnelling?
There are many types of VPN protocols that offer varying levels of security and other features. The most commonly used tunneling protocols in the VPN industry are PPTP, L2TP/IPSec, SSTP, and OpenVPN – and the world’s best VPN services should offer most or all of them. Let’s take a closer look at them.
How to configure IPsec tunnel?

What is IPsec tunnel and why use IPSec VPN?
