When the entries are created or updated, the flag
IP_CT_TCP_FLAG_BE_LIBERAL is set so that the window checking are
skipped, you should not get those "ACK/SEQ is under/over window". I
don't have an answer for the problem that you're reporting at this
moment. I know that there are some bugs in the ctnetlink code of 2.6.26
that were fixed in the subsequent kernel releases, but I did not know
any that affected the internal TCP flags set/unset. As these stuff is
under development, I suggest you to use the latest Linux kernel, please
let me know if the problem persists.

Filter From Kernelspace {
Protocol Accept {
TCP
}
Address Ignore {
IPv4_address 127.0.0.1 # loopback
}
}
It works here fine. Error reporting in the parsing is not very precise
yet, probably the problem is not in Filter but before (something is
missing and the parser gets confused). Could you post your config file
to reproduce it? You can send it to me in private if you want.
