Hi Harvinder,

This is probably not what you want (or what the Sonicwall expects).  If
you configure an IP like that charon will send it in a configuration
payload to the gateway to request it as virtual IP [1].  If you simply
want to use that IP inside the tunnel, just install it manually on one
of the interfaces (even lo).
