NAT 6-4

The vRouter supports NAT 6-4, a translator that allows IPv6-only networks to communicate with IPv4-only networks. The router forwards the IPv6 packets to the translator, which converts them into IPv4 packets. The response IPv4 packets flow in the opposite direction with the NAT6-4 translator converting IPv4 addresses into IPv6.

The following figure shows the flow of packets, which originate in an IPv6-only network.
