Canopy System User Guide Configuring an SM for the Destination
pmp-0229 (Mar 2013)
289
In the NAT tab of an SM with NAT enabled, you may set the following parameters.
NAT Enable/Disable
This parameter enables or disabled the Network Address Translation (NAT) feature for the SM.
NAT isolates devices connected to the Ethernet/wired side of an 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. For
further information, see Network Address Translation (NAT) on Page 158 and NAT and IP Tabs
of the SM with NAT Enabled on Page 287.
When NAT is enabled, VLANs are not supported on the wired side of that SM. You can enable
NAT in SMs within a sector where VLAN is enabled in the AP, but this may constrain network
design.
WAN Interface
The WAN interface is the RF-side address for transport traffic.
WAN Interface, Connection Type
This parameter may be set to
• Static IP—when this is the selection, the following three parameters (IP Address, Subnet
Mask, and Gateway IP Address) must all be properly populated.
• DHCP—when this is the selection, the information from the DHCP server configures the
interface.
• PPPoE—when this is the selection, the information from the PPPoE server configures the
interface.
WAN Interface, IP Address
If Static IP is set as the Connection Type of the WAN interface, then this parameter configures
the IP address of the SM for RF transport traffic.
WAN Interface, Subnet Mask
If Static IP is set as the Connection Type of the WAN interface, then this parameter configures
the subnet mask of the SM for RF transport traffic.
WAN Interface, Gateway IP Address
If Static IP is set as the Connection Type of the WAN interface, then this parameter configures
the gateway IP address for the SM for RF transport traffic.
