VPN negotiations happen in two distinct phases: Phase 1 and Phase 2. Phase 1. 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. If Phase 1 fails, the devices cannot begin Phase 2. Phase 2

ISAKMP (IKE Phase 1) status messages MM_WAIT_MSG# - … However, if the state goes to MSG6 then the ISAKMP gets reset that means phase 1 finished but phase 2 failed. Check that IPSEC settings match in phase 2 to get the tunnel to stay at MM_ACTIVE. AM_ACTIVE / MM_ACTIVE The ISAKMP negotiations are complete. Phase 1 has successfully completed. Phase 2 settings - Fortinet The basic Phase 2 settings associate IPsec Phase 2 parameters with a Phase 1 configuration. When defining Phase 2 parameters, you can choose any set of Phase 1 parameters to set up a secure connection and authenticate the remote peer. For more information on Phase 2 settings in the web-based manager, see IPsec VPN in the web-based manager. Networking Fundamentals: IPSec and IKE - Cisco Meraki Phase 2. Using the channel created in phase 1, this phase establishes IPSec security associations and negotiates information needed for the IPSec tunnel. This phase can be seen in the above figure as “IPsec-SA established.” Note that two phase 2 events are shown, this is because a separate SA is used for each subnet configured to traverse IKE Phase 2 - Palo Alto Networks

Page 1 of 3 - VPN tunnel failure - posted in Networking: I have been trying to set up my work phone at home, but I keep getting VPN tunnel failure. I have replaced modem, router, etc twice. It is

Our Phase 2 VPN tunnel is currently down. I dont realy have knowledge about IPSec. I am just basing from the internet to browse any infor about pFsense. I do not know what causes the Phase 2 VPN tunnel to unable to establish its connection to our another site. Usually if I restarted the IPSec Service and the VPN tunnels it should now turn its VPN Tunnel Setup on the RV016, RV042, RV042G and RV082 VPN Dec 10, 2018

IKE Phase 2 uses the keys that were established in Phase 1 of the process and the IPSec Crypto profile, which defines the IPSec protocols and keys used for the SA in IKE Phase 2.
