Hi Tobias,

thanks for your help. I just did and uninstall and install without options,
using same conf files, but with other internet provider, and now it works
as espected, in the second attempt.

Looks like the ipsec trafic was not allowed in that spot.

I didn't need to use leftsourceip=%config, since in the sonicwall profile
we use the option "Virtual adapter settings: DHCP Lease or Manual
Configuration".

I'll like to congratulate all of you for your effort.

I have the same conn configuration running in RHEL 6, centOS 6, openSUSE
13.2, ubuntu 14.4 and OSX 10.10. The only diference is that in ubuntu and
opensuse, our rigthid that uses espaces have to be "double quoted", because
it runs version 5.1.

Now I'm trying iOS and Android ;-)

Thanks again.
