Hi all,

I have setup a simple NAT-PT & it didnt work. any help

R1 -ipv6-------R2----ipv4----R4

R1 config:
--------------
interface FastEthernet0/0
 ip address 10.1.12.1 255.255.255.0
 duplex auto
 speed auto
 ipv6 address 2001:DB8:3002::1/64
 ipv6 enable

Rack1R1#sh ipv6 interface fas0/0
FastEthernet0/0 is up, line protocol is up
  IPv6 is enabled, link-local address is FE80::209:7CFF:FE72:4780
  Global unicast address(es):
    2001:DB8:3002::1, subnet is 2001:DB8:3002::/64
  Joined group address(es):
    FF02::1
    FF02::2
    FF02::1:FF00:1
    FF02::1:FF72:4780
  MTU is 1500 bytes
  ICMP error messages limited to one every 100 milliseconds
  ICMP redirects are enabled
  ND DAD is enabled, number of DAD attempts: 1
  ND reachable time is 30000 milliseconds
  ND advertised reachable time is 0 milliseconds
  ND advertised retransmit interval is 0 milliseconds
  ND router advertisements are sent every 200 seconds
  ND router advertisements live for 1800 seconds
  Hosts use stateless autoconfig for addresses.

R2 Configs:
--------------------

interface FastEthernet0/0
 ip address 10.1.12.2 255.255.255.0
 service-policy input policypolicetest
 duplex auto
 speed auto
 ipv6 address 2001:DB8:3002::2/64
 ipv6 enable
 ipv6 nat
!
Rack1R2#
Rack1R2#
Rack1R2#sh ipv6 nat trans
Prot IPv4 source IPv6 source
      IPv4 destination IPv6 destination
--- --- ---
      10.1.4.4 2001:DB8::2

--- 10.1.24.2 2001:DB8:3002::1
      --- ---

!
interface FastEthernet0/1
 ip address 10.1.4.2 255.255.255.0
 duplex auto
 speed auto
 ipv6 nat
end

R4 config:
---------------
Rack1R4#sh run inter e0/0
Building configuration...

Current configuration : 92 bytes
!
interface Ethernet0/0
 ip address 10.1.4.4 255.255.255.0
 half-duplex
 no cdp enable
end

problem:
----------------
Ping from R4 to 10.1.12.1 ...does not work.. ??????

Debugging:
--------------

Rack1R2#ping 10.1.12.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.12.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
Rack1R2#ping 2001:db8:3002::1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:DB8:3002::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
