[Openswan Users] openswan xauth problem with sonicwall

[Amlan Mandal]

Hi All,
I love linux. I really do. I know it is open source, lot of people has contributed voluntarily to make it better. But some time it does not meet the basic standards. I am sorry that I made the statement. But that is how it is. I am trying to run vpn on my Ubuntu 7.10 (gutsy) with openswan 1:2.4.6+dfsg.2-1.1build2  with Sonicwall VPN (xauth enabled). I can not disable xauth as it is company policy. 
After it does 
004 "sonicwall" #6: STATE_MAIN_I4: ISAKMP SA established {auth=OAKLEY_PRESHARED_KEY cipher=oakley_3des_cbc_192 prf=oakley_sha group=modp1536}

I guess it should as xauth authentication after this. Nothing happens it just gets stuck then I get 
003 "sonicwall" #6: next payload type of ISAKMP Hash Payload has an unknown value: 164
003 "sonicwall" #6: malformed payload in packet
002 "sonicwall" #6: sending notification PAYLOAD_MALFORMED to xxx.xxx.xxx.xxx:4500

I have tried all possible config it JUST does not work. After 5 days of work I could not make it work.

conn sonicwall
    type=tunnel
    left=10.0.0.2
    leftid=@GroupVPN
    leftxauthclient=yes
    rightxauthclient=yes
    right=x.x.x.x
    rightsubnet=192.168.1.0/24
    rightxauthserver=yes
    leftxauthserver=yes
    rightid=@xxxxxxxxxxx
    keyingtries=1
    pfs=yes
    aggrmode=no
    auto=add
    auth=esp
    esp=3des-sha1
    ike=3des-sha1-modp1536
    authby=secret
    xauth=yes

Is it ever going to work????
Hope it will.
Regards,
Amlan
