SOLVED: Pfsense 2.1.2 with CARP IPSEC VPN PROBLEM

  • C

    Hello

    I have the 2 Pfsense 2.1.2 in CARP.

    I would like to create a VPN IPSEC.

    I have a VPN_A
    My local IP: IP CARP
    Local network 172.16.0.0/12  to remote network 10.144.1.0/24    is working

    If I add a new vpn  VPN_B with Cisco ASA.
    from local network 172.22.0.0/16  to remote network 10.129.2.0/24  is  not work.

    In the LOG I see only this messages for the VPN_B

    pr 23 12:37:29 racoon: INFO: purged IPsec-SA proto_id=ESP spi=10237954.

    In the IPSEC:SAD I don't see any SA associations for the VPN_B

    I solved.

    I'm not sure that is this the problem but now is working.

    Change the My identifier with CARP IP.
