NAT-PT configuration examples
Configuring dynamic mapping on the IPv6 side
Network requirements
As shown in Figure 31 , SecPath C with IPv6 address 2001::2/64 on an IPv6 network wants to access
SecPath A with IPv4 address 8.0.0.2/24 on an IPv4 network, whereas SecPath A cannot actively access
SecPath C.
To meet the preceding requirements, you need to configure SecPath B 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 SecPath B so that IPv6 hosts can access IPv4 hosts but IPv4 hosts cannot access IPv6 hosts.
