said by DSL_Ricer:A brief check seems to indicate that even 2.6 might not support that.
Right, Linux doesn't. I've seen patches floating around a year or two back but haven't tried them.
Is there a reason why you need NAT in IPv6?
I need NAT in order to load balance TCP sessions between multiple ISPs. It isn't a problem right now since my other ISP doesn't support IPv6 (and won't for a while), but near as I can tell, NAT is the only option for small users.
