Provides stateless source IPv6-to-IPv6 Network Prefix Translation (as described

by RFC 6296).

.PP

You have to use this target in the

.B mangle

table, not in the

.B nat

table. It takes the following options:

.TP

\fB\-\-src\-pfx\fP [\fIprefix/\fP\fIlength]

Set source prefix that you want to translate and length

.TP

\fB\-\-dst\-pfx\fP [\fIprefix/\fP\fIlength]

Set destination prefix that you want to use in the translation and length

.PP

You have to use the DNPT target to undo the translation. Example:

.IP

ip6tables \-t mangle \-I POSTROUTING \-s fd00::/64 \! \-o vboxnet0

\-j SNPT \-\-src-pfx fd00::/64 \-\-dst-pfx 2001:e20:2000:40f::/64

.IP

ip6tables \-t mangle \-I PREROUTING \-i wlan0 \-d 2001:e20:2000:40f::/64

\-j DNPT \-\-src-pfx 2001:e20:2000:40f::/64 \-\-dst-pfx fd00::/64

.PP

You may need to enable IPv6 neighbor proxy:

.IP

sysctl -w net.ipv6.conf.all.proxy_ndp=1

.PP

You also have to use the

.B NOTRACK

target to disable connection tracking for translated flows.
