Vpnc: no response from target

[HAL9000]

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)
  PARSE_OK

vpnc: no response from target"

Any help with this would be greatly appreciated.
