Hi GS,
I configure NAT-PT as follow:
interface GigabitEthernet0/0
ip address 172.16.1.1 255.255.255.0
duplex auto
speed auto
ipv6 enable
ipv6 nat prefix 2001::/96
ipv6 nat
!
interface GigabitEthernet0/1
no ip address
duplex auto
speed auto
ipv6 address 2001:1:1::1/64
ipv6 enable
ipv6 nat
ipv6 nat v4v6 source 172.16.1.2 2001::20
ipv6 nat v6v4 source 2001:1:1::10 172.16.1.20
I can ping from IPv6 Host, but don't receive any reply:
R(config)#do sh ipv6 nat trans
Prot IPv4 source IPv6 source
IPv4 destination IPv6 destination

From IPv4 host, I ping:
HostIPv4#ping 172.16.1.20
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.1.20, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
From ROUTER NAT-PT, I can ping both:
R#ping 172.16.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
R#ping 2001:1:1::10
