Task 2: Configuring IP and Ethernet interfaces PMP 450i and PTP 450i Configuration and User
Guide
In the NAT tab of SM with NAT enabled, you may set the following parameters.
Table 12 SM with NAT enabled - NAT attributes
Attribute Meaning
NAT
Enable/Disable
This parameter enables or disabled the Network Address
Translation (NAT) feature for the SM. NAT isolates devices
connected to the Ethernet or 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 or
wired side of the SM.
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.
Connection Type
This parameter may be set to
Static IPwhen this is the selection, all three parameters
(IP Address, Subnet Mask, and Gateway IP Address) must
be properly populated.
DHCPwhen this is the selection, the information from the
DHCP server configures the interface.
PPPoEwhen this is the selection, the information from the
PPPoE server configures the 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.
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.
Reply to Ping on
WAN Interface
By default, the radio interface
does not
respond to pings. If
you use a management system (such as WM) that will
occasionally ping the SM, set this parameter to Enabled.
LAN Interface The LAN interface is both the management access through
the Ethernet port and the Ethernet-side address for transport
traffic. When NAT is enabled, this interface is redundantly
shown as the NAT Network Interface Configuration on
the IP tab of the Configuration web page in the SM.
