[Openswan Users] Problem with some road connection

[Sasa]

Hi, I have a problem with a road connection (with site-to-site it's ok) but 
it's very strange because this problem is present only with some road 
connection (with other road connection is all ok), when the vpn client is 
impossible connect to my vpn server I have in log:
