NAT, DHCP Server, DHCP Client and DMZ in SM
The system provides NAT (network address translation) for SMs in the following combinations of NAT and
DHCP (Dynamic Host Configuration Protocol):
l
NAT Disabled
l
NAT with DHCP Client (DHCP selected as the Connection Type of the WAN interface) and DHCP
Server
l
NAT with DHCP Client (DHCP selected as the Connection Type of the WAN interface)
l
NAT with DHCP Server
l
NAT without DHCP
NAT
NAT isolates devices connected to the Ethernet/wired side of a SM from being seen directly from the
wireless side of the SM. With NAT enabled, the SM has an IP address for transport traffic (separate from its
address for management), terminates transport traffic, and allows you to assign a range of IP addresses to
devices that are connected to the Ethernet/wired side of the SM.
In the Cambium system, NAT supports many protocols, including HTTP, ICMP (Internet Control Message
Protocols), and FTP (File Transfer Protocol). For virtual private network (VPN) implementation, L2TP over
IPSec (Level 2 Tunneling Protocol over IP Security) and PPTP (Point to Point Tunneling Protocol) are
supported.
