The first step in debugging filtering rules is to log all packets
which are denied or rejected, by adding a catch-all DENY (or REJECT)
rule to the end of any chain with a policy of DENY/REJECT, then adding
the "-l" switch to all DENY and REJECT rules.
BTW, you need to ensure that syslog actually logs those messages
somewhere, e.g. by adding
kern.info /var/log/kernel
to /etc/syslog.conf (and restarting syslogd).
