But I found the following problem: once the client is connected to VPN server for almost one hour the following SA changes occur: client connected at Jan 22 ~09:40 Jan 22 10:30:33 vpn01 racoon: INFO: IPsec-SA expired: ESP/Transport A

You should see that the VPN connection is established between your device (the local addr ) and the remote peer ( current_peer )

The differences between main, aggressive, and quick modes have to do with the degree of security needed and the number of messages exchanged

Ipsec Vpn Ipsec Sa Expired Esp Tunnel, Softether Vpn Server Manager Ubuntu, Configurar Vpn Teamviewer 13, Vpn W Niemczech To create a VPN you need IKE and IPsec tunnels or Phase 1 and Phase 2

This allows the processing of any inbound IPsec protected traffic that may still be on the wire

These resources are wasted during periods of IPSec endpoint inactivity which could result in the gateway’s inability to create new SAs for other endpoints; thereby, preventing new sessions from connecting

To avoid any drop in the traffic the device initiates a new SA

Both hosts then go into a loop: the local host trying to establish a phase 2 SA, the remote host trying to tell the local host that the ISAKMP-SA has expired

When phase 2 has auto-negotiate enabled, and phase 1 has mesh-selector-type set to subnet , a new dynamic selector will be installed for each combination of source and destination subnets

Soft lifetime - The soft lifetime defines the number of seconds until the IKE process is informed that the SA is about to expire

Re: Client VPN not working (MX64) I know this thread is a bit old now, but in case anyone else has the issue I had a user who had been connecting quite happily but then could not get in today

If your VPN fails to connect, check the following: Ensure that the pre-shared keys match exactly (see The pre-shared key does not match (PSK mismatch error) below)

The VPN Overview article provides some general guidance of which VPN technology may be the best fit for different scenarios

If the time-based lifetime and traffic-based lifetime are both set for an IPSec SA, the IPSec SA becomes invalid when either lifetime expires

The tunnel drops and the Palo Alto tries to re-initiate and fails

The virtual connectivity between the source and the destination host is set up before the exchange of data between them, and this connection is called security association (SA)
