[afnog] IPv6 NAT-PT ?

[Phil Regnauld]

Ok, so here I am, I want to run IPv6 -- I've got a tunnel set up with
HE.net (very much recommended), I've got 6to4 up and running, and I'm
running FreeBSD as a gateway.

I've got v6 only hosts for testing, and they want to access all the v4 sites

1. Is there a NAT-PT implem for FreeBSD ?
2. Is there one for Linux otherwise ?
3. Any good pointers to setup, possibly on other platforms (IOS, etc...) ?
