tcpdump filter not ignoring jail subnet

[Beeblebrox]

I got out of my logic-loop and solved my filter problem.
Thanks everyone for thier input.

((src net not 192.168.1.0/24 and host not 192.168.2.97 and not ip6) or
host mybsd) and not port (imap or imaps or 6667)

Below syntax is not accepted by tcpdump, btw:
src not (net 192.168.1.0/24 and host 192.1-----)
tcpdump does not seem to accept other keyword between "not" and the variable.

Regards.
