[Openswan Users] Connecting to a VPN through Ubuntu

[Rogelio Alejandro Ortiz Sevilla]

Good day to everyone, some days ago I sent an email which was kindly
responded by mr. Paul Wouters. He was right, I had a lot of misconfiguration
on my */etc/ipsec.conf file.* Now, I have followed the Ubuntu and SonicWall
VPN configuration on this site, step by step:

http://www.pelagodesign.com/blog/2009/05/18/ubuntu-linux-how-to-setup-a-vpn-connection-to-a-sonicwall-router-using-openswan-and-pre-shared-keys-psk/


which led me to have this content on the */etc/ipsec.conf file:

conn sonicwall
     type=tunnel
     left=127.0.0.1
     leftid=@GroupVPN
     leftxauthclient=yes
     right=MySonicWallIP
     rightsubnet=MyGateWayIP/24
     rightxauthserver=yes
     rightid=@sonicwall.unique.identifier
     keyingtries=0
     pfs=yes
     aggrmode=yes
     auto=add
     auth=esp
     esp=3DES-SHA1
     ike=3DES-SHA1
     authby=secret


And this content on the **/etc/ipsec.secrets file*
*
@GroupVPN @sonicwall.unique.identifer : PSK "MyPreSharedKey"
*

After having my router and my openswan files configured like previously
stated, i tried to start the vpn using these commands:


sudo ipsec setup --start
sudo ipsec auto --add sonicwall
sudo ipsec whack --name sonicwall --initiate


After this I get the following output:

003 "sonicwall" #1: multiple transforms were set in aggressive mode. Only
first one used.
003 "sonicwall" #1: transform (5,2,2,0) ignored.

I have Ubuntu 10.04 installed, my ipsec --version command throws the
following output:

Linux Openswan U2.6.23/K2.6.32-33-generic-pae (netkey)


I installed openswan thorugh the ubuntu repositories. Am I missing
something???, any help would be greatly appreciated :-D


Thanks a lot in advance for your time.
