What is PRF in Cisco ASA?

PRF: For IKEv2, a separate pseudo-random function (PRF) used as the algorithm to derive keying material and hashing operations required for the IKEv2 tunnel encryption. The options are the same as those used for the hash algorithm; Thank you.

How do I setup a website for IPsec VPN?

Let us examine each of the above steps.

  1. Step 1: Creating Extended ACL. Next step is to create an access-list and define the traffic we would like the router to pass through the VPN tunnel.
  2. Step 2: Create IPSec Transform (ISAKMP Phase 2 policy)
  3. Step 3: Create Crypto Map.
  4. Step 4: Apply Crypto Map to the Public Interface.

What is the difference between Phase 1 and Phase 2 in IPSec?

What happens in Phase 1 of IPSec VPN?

The Phase 1 negotiation process depends on which version of IKE the gateway endpoints use. IKE authenticates IPSec peers and negotiates IKE SAs during this phase, setting up a secure communications channel for negotiating IPSec SAs in Phase 2.

What is an IPSec VPN and how does it work?

PPTP. Point to Point Tunneling Protocol — better known as PPTP — is one of the oldest versions still in use today.

  • L2TP/IPSec. Layer 2 Tunneling Protocol,when used with Internet Protocol Security,is a step up from basic PPTP.
  • SSTP. Secure Socket Tunneling Protocol is unusual because it is only available on Windows operating systems.
  • OpenVPN.
