IPv6 NPT and NAT for Linux

Wed Nov 30 20:14:07 UTC 2011

For those who missed it, Linux is adding NAT for IPv6 to netfilter:

Along with tradition SNAT, and DNAT targets most of us are familiar
with, a new NETMAP target is included that implements NPT (network
prefix translation).

I for one am happy to see this; despite not wanting to see people NAT
IPv6 as the norm, having the NETMAP target will largely replace the
use of SNAT and MASQUERADE for many deployments, while keeping those
tools for the times when traditional NAT is desirable.
