SPA2102 and PAPAT2 v6 support or double nat?

[DonGouldNZ]

I'm setting up a little wireless network/isp concept with limited v4 address space.

So I'm looking at using double nat.

All was going well until I pluged my PAPAT2 in behind the second router. 

So what I'm keen to know is:

- is double nat doable or am I chasing tail?

- can I look at just using ipv6?

I haven't seen any settings in my current firmware for v6 settings on either unit, though I confess I'm quite new to these units.

Can anyone comment?

Double nat should work ok.  Currently, I do have a SPA500 series phone behind a second router and it's working fine.

IPv6 isn't available on the current product line.
