(racoon 712) Strange behaviour

Hello all,

im testing a tunnel between 2 wireless networks using raccon,
everythings working fine, but verifying the traffic i see sometimes that
a packet travels in clear, this is what ethereal shows.

The thing i sthat i see no reply packet in clear text ... .-O

835 packets transmitted, 826 packets received, 1% packet loss
round-trip min/avg/max = 7.2/12.2/57.3 ms

And i dont see any problem on the connection, except really few packets
lost.

Any ideas about whats happening ???

TIA
CHeers
