[Openswan Users] Ipsec service breaks when the windows connection are closed.

[jffr]

Hi,
  
  I have a problem with a VPN (roadwarrior) connection between an windows XP Porfessional and my firewall with vpn support.
  I have installed L2TP, Openswan (with IPSEC), kernel 2.4.20 in a debian SO.

 
  First sorry for my bad english (I'm Portuguese), ok, the problem is:

   I create a connection with the vpn windows XP wizard then i configure it with  a few options. I stablish the vpn tunnel without any problems, in my windows i can launch an ssh console to a computer on my private network. The problem is when i close this connection on windows, the IPSEC service running in my linux firewall server (ipsec setup start) goes down and every connections to my sever are closed. I don't know if this is a configuration problem (in ipsec.conf) or a bug.

Any ideas ?
