Hello,

I forgot to set address family in libxt_tproxy.c (match), but
libxt_TPROXY.c (target) works well.
Patch is attached.

You should use the target as:

iptables -t tproxy -A PREROUTING -p tcp <other options> -j TPROXY <other
parameters>
or
iptables -t tproxy -A PREROUTING -p udp <other options> -j TPROXY <other
parameters>

and
iptables -A INPUT -m tproxy -j ACCEPT

TPROXY target should  be used only in the tproxy table's PREROUTING
chain and tproxy match should be used in filter table's INPUT chain.
Also you shouldn't write  ... -m tproxy ... -j TPROXY
