Vpnc: no response from target

  • I  have not be able to for a tunnel using vpnc or shrew soft. I have made sure that the correct ports are open, the user I'm trying to log in has the correct permissions (User - VPN - IPsec xauth Dialin), and my config is correct. Yet I cannot get the tunnel to come up for some reason.

    nmap of the server

    # nmap -sSU <gateway ip=""> -p500,4500
    Starting Nmap 6.40 ( http://nmap.org ) at 2014-10-01 10:57 EDT
    Nmap scan report for <gateway ip="">
    Host is up (0.017s latency).
    PORT     STATE         SERVICE
    500/tcp  filtered      isakmp
    4500/tcp filtered      sae-urn
    500/udp  open|filtered isakmp
    4500/udp open|filtered nat-t-ike</gateway></gateway>

    vpnc config file being used:

    IPSec gateway <gateway ip="">IPSec ID <username@domain>IPSec secret [secret]
    IKE Authmode psk
    Xauth username <username@domain># same as above
    Xauth password [secret] #same as above
    #Vendor netscreen</username@domain></username@domain></gateway> 

    Here is a link to the debug out put of vpnc


    Here is a link to relevent parts of racoon.conf


    Basically the output of vpnc ends with "PARSING PAYLOAD type: 00 (ISAKMP_PAYLOAD_NONE)

    vpnc: no response from target"

    Any help with this would be greatly appreciated.
