If you use `--with-suite-b` our own userland IPsec implementation will
be used instead of the kernel's via PF_KEY. So you won't see any output
in `setkey -D` (also you'd have to run that command as superuser with sudo).

Looks like Sonicwall sends an INITIAL_CONTACT in an INFORMATIONAL
exchange during the XAuth exchange (and even though it is the server).
Apparently, charon has trouble handling this properly. In the second
try the Sonicwall perhaps still has the state from the first attempt
around and therefore does not send the notify.

You might need to request a virtual IP address  from the server using
`leftsourceip=%config`, which is usually the case in remote access
