I have a cisco router 2800 as my default gateway in my LAN. IPv4 is the format of the addesing in the LAN and the WAN interface. But now, the WAN conectivity will be IPv6.
The actual diagram is the folowing:
LAN: 172.16.30.X/23 ---ipv4-LAN--> f0/0(Router)f0/1---ipv4-WAN-->
The router 2800 has a defaul router: 0.0.0.0 0.0.0.0 f0/1
The diagram will be:
LAN: 172.16.30.X/23 ---ipv4-LAN--> f0/0(Router)f0/1---IPV6-WAN-->
How enable the ipv6 routing in the 2800 Routers?
What I need?

You will need to check your 2800's software to see if the following command is available
ipv6 unicast-routing
This will turn on IPv6 routing, and you can assign IPv6 address and configure IPv6 default route on your router.
You also need IPv4 to IPv6 NAT to be configured.
Please see the following link on how to configure IPv6 in IOS 12.4

Yes, the command is supoorted in the Cisco Roter 2800.
My configuration is the following:
ip dhcp excluded-address 172.16.30.1 172.16.30.10
ip dhcp pool lan
network 172.16.30.0 255.255.255.0
default-router 172.16.30.1
interface FastEthernet0/0
description ***LAN***
ip address 172.16.30.1 255.255.255.0
ip nat inside
!
interface FastEthernet0/1
description ***WAN***
