IPv6 NAT-PT

Hi,

I have a requirement to test a server using it's ipv6 interface for
DNS querying. The DNS server is ipv4 and has mostly ipv4 data and A
records. This seemed like a good opportunity to try out NAT-PT.

It seems that there is a built-in ALG which recognizes the DNS and
converts A queries to AAAA. Some packets are converted and some are
(silently) dropped. Is there some way to disable the ALG or another
method of some simple static ipv6<>ipv4 Natting on the transport layer
only?
