[Users] another problem with NAT-T

Hi,

the configuration is like this

[subnet A] ---- [host A] ---ppp link---[Internet] ----[host B] ----
[subnet B]

host A receives private IP addresses so I have to use NAT-T
and it works

but a problem starts when the ppp link breaks

I make another ppp connection and start freeswan
I try to set up ipsec connection again (initiating from host A) and it
just doesn't work
host A sends #1: STATE_MAIN_I1: initiate, but gets no responses

host B receives the packets, but freeswan at host B seems not to react
to them

when I stop the old connection at B, and start it again it still doesn't
work

B still doesn't react to A trying to inititate another SA

anyway, when I give up trying, and wait for some time
i start everything up again

and then it works, even though freeswan at B wasn't restarted (all I did
was stoping and adding connection)

to me it looks quite "indeterminate"
but maybe somebody had a similar problem
or have any idea, of what I might do wrong, or what else should I check

Kuba
