How do I create an IPSec tunnel?

Preshared key authentication

1. In the administration interface, go to Interfaces.
2. Click Add > VPN Tunnel.
3. Type a name of the new tunnel.
4. Set the tunnel as active and type the hostname of the remote endpoint.
5. Select Type: IPsec.
6. Select Preshared key and type the key.

How does IPSec tunnel 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 IPSec works step by step?

Interesting traffic initiates the IPSec process—Traffic is deemed interesting when the IPSec security policy configured in the IPSec peers starts the IKE process….

1. Step 1: Defining Interesting Traffic.
2. Step 2: IKE Phase One.
3. Step 3: IKE Phase Two.
4. Step 4: IPSec Encrypted Tunnel.
5. Step 5: Tunnel Termination.

How IPsec works step by step?

Why do we need 2 phases in IPSec?

The purpose of Phase 2 negotiations is for the two peers to agree on a set of parameters that define what traffic can go through the VPN, and how to encrypt and authenticate the traffic. This agreement is called a Security Association.

Why do we need two phases in IPSec?

VPN negotiations happen in two distinct phases: Phase 1 and Phase 2. The main purpose of Phase 1 is to set up a secure encrypted channel through which the two peers can negotiate Phase 2. When Phase 1 finishes successfully, the peers quickly move on to Phase 2 negotiations.

What is a Phase 1 and Phase 2 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 are disadvantages of IPSec?

However, IPSec has two major drawbacks. First, it relies on the security of your public keys. If you have poor key management or the integrity of your keys is compromised then you lose the security factor. The second disadvantage is performance.

What protocols does IPSec use?

IPsec is a suite of protocols widely used to secure connections over the internet. The three main protocols comprising IPsec are: Authentication Header (AH), Encapsulating Security Payload (ESP), and Internet Key Exchange (IKE).

What protocols does IPsec use?

What are the benefits of IPsec in a network?

IPsec provides the following security services for traffic at the IP layer: Data origin authentication—identifying who sent the data. Confidentiality (encryption)—ensuring that the data has not been read en route. Connectionless integrity—ensuring the data has not been changed en route.
