..but about my error:

Dec 15 13:20:49 fw pluto[2384]: ERROR: asynchronous network error report on
eth0 (sport=4500) for message to 1.2.3.4 port 4500, complainant 5.6.7.8: No
route to host [errno 113, origin ICMP type 11 code 1 (not authenticated)]

..if is better to use parameter virtual_private or not ??
Do you think that my error is originate from virtual_private= line is 
missing ?
thanks.
