Hi

1) I have transferred (copied) the /etc/ipsec.d directory structure of a
running FreeSWAN (Gateway A) to another fresh installed FreeSWAN (Gateway B)
gateway.
2) I transferred the the ipsec.secrets file from Gateway A to Gateway B (for
pointing the key file) as well.
3) Restarted the ipsec pluto, expecting the Win2k client of the previously
running gateway (Gateway A) would connect to this new gateway (Gateway B) as
well.

When I try to connect from Win2K client,ipsec barf gives me the following
error.

I1 message is unacceptable because it uses a previously used Message ID
