perhaps it's covered in some place here (if so, could you please point to the right direction) - is entry iptables_tproxy.ko missing under tproxy 4.x.x version (so things like 'iptables -F tproxy -L' cannot be called)? I can see, for instance, 'iptables_raw' etc, but not the above in my /lib/modules/... directory.
Thanks,
Alex.
