free/swan problem

[Marco_113]

Hi all,
i've a problem with VPN.
I try to establish a connection beetween a Linux Gateway and a Laptop (winxp) with dynamic IP.

on linux:

ipsec.secrets:

IP_public_gw 0.0.0.0 : PSK "xxxxxxxxxxxxxxxxx"
IP_public_gw %any : PSK "xxxxxxxxxxxxxxxxxx"


ipsec.conf

conn harpa-marco
type=tunnel
left=0.0.0.0
leftsubnet=
leftnexthop=
authby=secret
right=IP_gw_public
rightsubnet=192.168.10.0/24
rightnexthop=IP_gw_next_hop

On Laptop i configure the vpn with configuration wizard
Start->Programs->Communications->New_connection

When i try to connect with the laptop to VPN i get on Linux gw /var/log/secure

responding to Main Mode from unknown peer 213.45.193.115

Dec 15 18:04:50 gw-1 pluto[10769]: "harpa-marco"[3] 213.45.193.115 #9: Quick Mode I1 message is unacceptable because it uses a previously used Message ID 0x097c1087 (perhaps this is a duplicated packet)

Any suggestion??
Thanks
