Hello..

I've tried to lab this CCIE TO BE: IPv6 NAT-PT
Same configs as on the website.. pings fail..ie: from R1 to 2001:23::2 ?


R3#sh run | i ipv6
ipv6 unicast-routing
ipv6 address 2001:12::3/64
ipv6 enable
ipv6 nat
ipv6 nat
ipv6 nat v4v6 source 192.168.23.2 2001:23::2
ipv6 nat v6v4 source 2001:13::1 192.168.13.1
ipv6 nat prefix 2001:23::/96
R3#sh ipv6 int br
FastEthernet0/0            [up/up]
FE80::CE02:4FF:FEDC:0
2001:12::3

R3#sh ip int br
Interface                  IP-Address      OK? Method Status                 Protocol
FastEthernet0/0            unassigned      YES unset  up                     up
FastEthernet0/1            192.168.23.3    YES manual up                     up
NVI0                       unassigned      NO  unset  up                     up

Gateway of last resort is not set

C    192.168.23.0/24 is directly connected, FastEthernet0/1
R3#sh ipv route
IPv6 Routing Table - 4 entries
Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP
U - Per-user Static route
I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS  summary

ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2
C   2001:12::/64 [0/0]
via ::, FastEthernet0/0
L   2001:12::3/128 [0/0]
via ::, FastEthernet0/0
L   FE80::/10 [0/0]
via ::, Null0
L   FF00::/8 [0/0]
via ::, Null0

R3#sh ipv6 nat translations
Prot  IPv4 source              IPv6 source
IPv4 destination         IPv6 destination
