[Openswan Users] OpenSWAN - Cisco Pix Group ID VPN

Hi All!

Having set up a few connections to a Cisco pix previously, this one is 
causing me trouble. The difference here is the Cisco VPN group. Reading 
on the net it seems this should be possible to be done. There's no xauth 
on the pix, only VPN group and PSK.

So, any idea what I can have missed?

Current OpenSWAN config:
          authby=secret
          right=1.2.3.4
          rightsubnet=192.168.0.0/24
          rightid=@pix.cisco.com #also tried with no rightid
          leftid=@vpngroup1
          left=%defaultroute
          auto=start #also tried with add and then use whack to start it
          pfs=no
          esp=3des-md5-96

Also tried setting the following options on and off:
       #rightxauthserver=yes
       #rightmodecfgserver=yes
       #leftxauthclient=yes
       #leftmodecfgclient=yes
       #ike=3des-md5
       #modecfgpull=yes
       #keyexchange=ike

Secret file:
: PSK "mysecret"
(also tried setting with IP, ID)

Cisco Pix vpngroup configuration:
vpngroup vpngroup1 address-pool VPNP
vpngroup vpngroup1 dns-server 192.168.0.4
vpngroup vpngroup1 split-tunnel vpn_client
vpngroup vpngroup1 idle-time 1800
vpngroup vpngroup1 password ********
