Help on Simple NAT64 configuration

[KR SHAH]

Kindly guide us on implementation of IPv6. Which configuration we require to do as there 2 option here. One is NAT-PT and other is NAT 64.As per our knowledge we require to configure NAT64 on both interface as show in figure. we configure also IPv6 Unicast routing.? what else we require to configure regarding IPv6 so USER A can access web server over IPv6.

Please suggest what other configuration that are require to do.?

Thanks

No, what we understood from above example that i explain to you. After configuring abve configuration Part, the IPV6 user able to take RDP of IPv4 with IP of 2001:178:178::1.

In configuration the IPv4 user NATed with IPv6 2001:178:178::1.

But what if I have only one pool for wan 2001:470:C021:1::1/64.

can i modified above configuration like this

interface GigabitEthernet0/0
 description ipv6 lan
 no ip address
 ip flow ingress
 ip flow egress
 ip virtual-reassembly in
 duplex auto
 speed auto
   ipv6 address 2001:470:C021:1::1/64
 ipv6 enable
 ipv6 nat

!
interface GigabitEthernet0/1
 description  lan
 ip address 192.168.0.1 255.255.255.0
 duplex auto
 speed auto
 media-type rj45
 ipv6 enable
 ipv6 nat
end

ipv6 access-list myv6
    remark   ipv6 internal network
    permit ipv6 2001:470:C021:1::/64 any

ipv6 nat v4v6 source 192.168.0.2 2001:470:C021:1::4
ipv6 nat v6v4 source list myv6 interface GigabitEthernet0/1 overload
ipv6 nat prefix 2001:470:C021:1::/96

Note: We Just use One router .  Ipv4 LAN------>Router-------> IPv6 LAN

Can we do configuration like this.? or we need to require some more config.

Thanks,

I'm not sure.  I would be trying what you have suggested.

Can you ask the ISP for another IPv6 /64 prefix?  Then you don't need NAT64 ... and even if you really really want NAT64, you will have a unique prefix for it.

Sorry just read this again, yes you should use something like:

 ipv6 nat v4v6 source 192.168.0.2 2001:470:C021:1::4
