OSBRiDGE 5GXi, Configuration Manual

Page: 9 / 32

Polling Client – This mode allows connection to OSBRiDGE 5G device, utilizing
proprietary polling wireless mac protocol, that has been specifically optimized for high
performance outdoor networks.
AP Client – This mode allows connection to OSBRiDGE 5G device and full MAC address
passthrough in Bridge mode.
PtP Bridge Master – This mode allows creation of a point to point connection with
another OSBRiDGE 5XLi/5GXi or OSBRiDGE 5Gi device operating in Slave (or Client)
mode. Please note that entering preferred BSSID is mandatory in this mode.
PtP Bridge Slave – This mode allows creation of a point to point connection with another
OSBRiDGE 5XLi/5GXi or OSBRiDGE 5Gi device operating in Master mode. Please note that
entering preferred BSSID is mandatory in this mode.
IP Operational Mode –
Bridge - Bridge works at OSI model Layer 2. This means it does not know anything about
protocols, but just forwards data depending on the destination address in the data packet.
This address is not the IP address, but the MAC (Media Access Control) address that is
unique to each network adapter card. With a Bridge, all your computers are in the same
network subnet, so you don't have to worry about not being able to communicate
between computers or share an Internet connection. The only data that is allowed to cross
the bridge is data that is being sent to a valid address on the other side of the bridge.
Bridges don't require programming. They learn the addresses of the computers
connected to them by listening to the data flowing through them. Bridges are very useful
for joining networks made of different media types together into larger networks, and
keeping network segments free of data that doesn't belong in a particular segment.
Router - Router is an OSI model Layer 3 device, and forwards data depending on the
network address, not the hardware (MAC) address. For TCP/IP networks this means the
IP address of the network interface. Routers isolate each LAN into a separate subnet.
Routers provide bandwidth control by keeping data out of subnets where it doesn't
belong, however routes need to be set up before they can get going.
NAT Router – This mode is similar to the Router mode only that all traffic coming on
wired interface and going out on wireless interface is masqueraded. Masquerade allows a
set of machines to invisibly access the Internet via the gateway (OSBRiDGE device in this
case). To other machines on the Internet, all this outgoing traffic will appear to be from
the OSBRiDGE device itself. In addition to the added functionality, IP Masquerade provides
the foundation to create a fairly secure networking environment.
DHCP – Enable or disable built in DHCP client/server.
DHCP Relay – In IP Router/NAT Router mode enable DHCP Relay so DHCP requests coming
from the LAN subnetwork will be relayed to the WLAN subnetwork and DHCP Server replies will
be relayed back to the LAN interface. If no specific DHCP server IP address is configured (default
value 0.0.0.0) then DHCP requests will be relayed to any DHCP server on the WLAN address. If
the DHCP server IP address is configured then all DHCP requests will be relayed to that
particular DHCP server.
Firewall – Enable or disable built in packet filtering firewall.
PPPoE Authorization – Enable or disable device built in PPPoE client:
-
In IP Bridge mode, if PPPoE is enabled, the device will authorize itself to the PPPoE
concentrator and establish a PPP link to it. Ethernet traffic will be bridged as usual.
-
In IP Router mode, if PPPoE is enabled, the device will authorize itself to the PPPoE
concentrator and establish a PPP link to it – over the wireless interface in the Access
Point Client mode or over the wired interface in the Access Point mode, PPPoE link will
be then used as a default gateway by the device. While operating in Router/Access
Point Client all traffic originating from the wired LAN subnetwork will be transported
over PPPoE link to the PPPoE concentrator.
