1Provides stateless destination IPv6-to-IPv6 Network Prefix Translation (as 2described by RFC 6296). 3.PP 4You have to use this target in the 5.B mangle 6table, not in the 7.B nat 8table. It takes the following options: 9.TP 10\fB\-\-src\-pfx\fP [\fIprefix/\fP\fIlength] 11Set source prefix that you want to translate and length 12.TP 13\fB\-\-dst\-pfx\fP [\fIprefix/\fP\fIlength] 14Set destination prefix that you want to use in the translation and length 15.PP 16You have to use the SNPT target to undo the translation. Example: 17.IP 18ip6tables \-t mangle \-I POSTROUTING \-s fd00::/64 \! \-o vboxnet0 19\-j SNPT \-\-src-pfx fd00::/64 \-\-dst-pfx 2001:e20:2000:40f::/64 20.IP 21ip6tables \-t mangle \-I PREROUTING \-i wlan0 \-d 2001:e20:2000:40f::/64 22\-j DNPT \-\-src-pfx 2001:e20:2000:40f::/64 \-\-dst-pfx fd00::/64 23.PP 24You may need to enable IPv6 neighbor proxy: 25.IP 26sysctl -w net.ipv6.conf.all.proxy_ndp=1 27.PP 28You also have to use the 29.B NOTRACK 30target to disable connection tracking for translated flows. 31
