strange behaivor ipfw2 counters

[dawnshade]

Hello all,

FreeBSD 4.9-RELEASE-p7, with ipfw2 in kernel.
I have 2 counters:

00001     5900     1623729 count ip from any to any in recv cp1
00002      130        9768 count ip from any to any out xmit cp1

cp1 - external interface, no nat, route real IP adresses.
When i download via http from this router counter 2 increasing, but when
download from client behind this router via ftp counter 2 increasing, but
_very_ small. This value (9768) i got after downloading ~3.5 Meg.
No any dynamic routing, only one channel to world:

<here i DL>-|internet|-(cp1 router fxp0)-<from this client i DL>
                                        \-<more clients>

All computers above have a real IP adresses.
What I doing wrong??
Try to search any PR, but didn't find :(

P.S. Sorry for terrible English.
