Pfsense <->pfsense, VPN established, no traffic -> suddenly traffic

  • Hey,

    I setup up an IPsec between 2 pfSense (newewst version 2.3.1), I configured it like recommended on book).
    So the tunnel is ready, connection is established, both IPSec firewall have an "any - any" rule - but I can't reach a client via ping.
    But from one point to another it start working and I can ping my client on the other side.

    After some time it doesn't work again, but pfsense says that the connection is still established.

    Do you have an idea where can I look for the issue?


  • I guess I got it -> it was a problem with the package HA-proxy.
    After uninstalling it, I don't have those effects.
