Using NAT-PT
Enables transparent communication between IPv6 and IPv4 hosts
- Still a NAT with all its evils
- IPv6 to IPv6 now possible!
- Communication is transparent to hosts
- Public DMZs can still be accessed using IPv4 through static or dynamic inbound mappings
Converting Today
- Deploy IPv6 internally
- Deploy NAT-PT
- Use tunneling/native IPv6 to connect to other IPv6 networks
Notes:
The communication through NAT-PT is transparent to the hosts on both ends and even public DMZ can be accessed through IPv4 if you configure NAT-PT to create inbound mappings.
In order to convert today, deploy IPv6 internally, obtain an IPv6 tunnel or native connection from your ISP. When upgrading your internal network, demand support for IPv6, and successively replace equipment that is not IPv6 compatible, until you are able to drop IPv4 from your network completely.
