+Особенности применения ip6tables
+--------------------------------
+
+ip6tables работают почти точно так же, как и ipv4, но есть ряд важных нюансов.
+В DNAT следует брать адрес --to в квадратные скобки. Например :
+
+ iptables -t nat -I OUTPUT -p tcp --dport 80 -m owner ! --uid-owner tpws -j DNAT --to [::1]:1188
+ 
+Параметра route_localnet не существует для ipv6.
+DNAT на localhost (::1) возможен только в цепочке OUTPUT.
+В цепочке PREROUTING DNAT возможен на любой global address или на link local address того же интерфейса,
+откуда пришел пакет.
+NFQUEUE работает без изменений.
