Enable Concurrent NAT/NAPT
Note You can define concurrent NAT/NAPT on only one WAN interface.
Typically, NAT may be used to make a single LAN-side host visible on the WAN, and NAPT makes
multiple hosts visible. Your service provide may also offer concurrent NAT/NAPT wherein a single
WAN interface may support multiple NAT connections, each of which makes a single LAN-side host
visible on the WAN. Through either NAT or NAPT, the router ensures that the LAN-side host is known
to the WAN only through the public IP address of the router’s WAN-side connection. The host’s actual
private IP address remains unknown to any WAN-side hosts or servers.
