Network address translation (NAT) lets a Cayman 2E-H conceal the
topology of an Ethernet network connected to its LAN interface
from routers on networks connected to its WAN interface.
topology of an Ethernet network connected to its LAN interface
from routers on networks connected to its WAN interface.
When NAT is enabled, the Cayman 2E-H “proxies” for computers on
your network by pretending to be the originating host for network
communications from non-originating networks. The Cayman 2E-H
tracks which local hosts are communicating with which remote
hosts, and routes packets received from remote networks to the
correct computer on the LAN (Ethernet A) interface. Sites
communicating through an Internet service provider typically
enable NAT, since they often receive one IP address from the ISP.
