NAT-PT ipv6 - arp problems?

hello I'm trying to use NAT-PT in order to ping a IPV4 address from my IPV6 network.

IPV6 routing is ok, and the icmp is hiting the ipv4 interface (debug ip icmp).

Everything works fine, until the router in the IPV4 has to find the IPV4 using arp. (debug arp)

the router doing nat is not respoding to the arp request from the router on ip.

I'm using the following configs:

ipv6 nat v4v6 source 172.16.34.3 FEC0:0:0:4444::3

ipv6 nat v6v4 source FEC0::B:0:0:10:6 172.16.34.6

ipv6 nat prefix FEC0:0:0:4444::/96

Any clues?

on 172.16.34.3 I can see the icmp packets with source 172.16.34.6. but Im getting a encapsulation failed (its not receiving a arp entry for that ip).
