Why prefer old SA ? Tunnel between Pfsense RC3 doesn't work properly!

  • I have a Ipsec tunnel between two Pfsense 2.0 RC3 (one is a PC, one is a Alix board).

    When the Alix board restart, the tunnel comes up but the PC will prefer old SA and the traffic will not go trough the tunnel… If I disable the option "prefer old SA" on the PC everything is working well, even after reboot the Alix board.

    Is it a normal behavior or is it a bug ?  ???

    Thanks  ;D

  • Hi,

    thats why i never enable this option. I got same problems with tunnels to multiple vendors. After Ike lifetime expired tunnels dont reconnect.

    I dont know why its checked by default. I would advice not to check this option.
