NAT-PT configuration examples
Configuring dynamic mapping on the IPv6 side
Network requirements
As shown in Figure 83, Router B with IPv6 address 2001::2/64 on an IPv6 network wants to access
Router A with IPv4 address 8.0.0.2/24 on an IPv4 network, whereas Router A cannot actively access
Router B.
To meet the preceding requirements, you need to configure LB that is deployed between the IPv4 network
and IPv6 network as a NAT-PT device, and configure dynamic mapping policies on the IPv6 side on LB
so that IPv6 hosts can access IPv4 hosts but IPv4 hosts cannot access IPv6 hosts.
