AWS VPC second tunnel drops after certain amount of time (therefore receiving AWS notifications regarding VPN connections now and then)

  • I am wondering if I am the only one having this issue or not.

    After some time, the 2nd IPsec tunnel is disconnected on the PFSense side. Click connect and they reconnect fine. Other than that everything works fine. It isn't VPC related because we have 3 different VPCs and consequently 6 differents tunnels and after some time we always end up with only one tunnel up on each VPC...

    We tried to ping a target to keep both tunnels up but same deal. (Automatically ping host in P2 advanced config)

    • Netgate SG-3100
    • 2.4.1-RELEASE (arm)

    Any ideas what it could be?


  • LAYER 8 Netgate

    Look at the IPsec logs and see who is requesting it be torn down and why.

  • Hi,

    Unfortunately, it does not happen often and the logs are quite verbose. By default it seems to only save a few thousands lines locally on the pfsense. If had some information I would have shared it.

    Right. Sometimes you need to log to an external server to solve issues like this.
