try to get more logging information,
then you should see what is dropped in the syslog:

> > FW_LOG_DROP_CRIT="yes"
> > FW_LOG_DROP_ALL="no" <<-- set this to yes

> > FW_LOG_ACCEPT_CRIT="yes"
> > FW_LOG_ACCEPT_ALL="no" <<-- maybe even this, too
> > FW_LOG="--log-level warning --log-tcp-options --log-ip-option
> > --log-prefix SuSE-FW"

Then check which rule that might be: iptables -vnL | less -S
and find the conf option that causes the rule...
