Ubuntu, Sonicwall, and OpenSwan Part 1

I am attempting to get OpenSwan on Ubuntu 10.04 to connect to a Sonicwall appliance at my Windows-centric office so I can work remotely from an Ubuntu-based laptop (read part 0).

I resurrected one of my old machines (20th anniversary shuttle), discovered the hard drive was shot, found an old 60GB IBM DeskStar EIDE hard drive lying around, popped it in, and installed Ubuntu 10.04, then installed OpenSwan a la
sudo apt-get install openswan

No issues with that install.

I edited /etc/ipsec.conf as specified by OpenSwan:

conn sonicwall
   type=tunnel
   left=XXX.XXX.XXX.XXX #my ubuntu machine IP
   leftid=@home
   leftxauthclient=yes
   right=xxx.xxx.xxx.xxx #IP address of my sonicwall router
   rightsubnet=192.168.X.0/24 #office subnet
   rightxauthserver=yes
   rightid=@sonicwall.unique.identifier #this ID is listed in the sonicwall admin interface
   keyingtries=0
   pfs=yes
   aggrmode=yes
   auto=add
   auth=esp
   esp=3DES-SHA1
   ike=3DES-SHA1
   authby=secret

Then I went into /etc/ipsec.secrets and added the secret code to it:
@home @sonicwall.unique.identifer : PSK "sooper.secret.shared.secret.key"

I started the connection up and opened it. Well, crappers:

Informational Exchange message must be encrypted, huh. Whatever can that mean?

What do you think?
