are:
Infrastructure Client - This mode allows connection to any 802.11a based Access Point.

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.

PPPoE Username/Password – A PPPoE Username and Password that are required to create
PPP link to the PPPoE concentrator.
Currently supported PPPoE authorization types are CHAP, PAP, MSCHAP and MPPE.
Watchdog – If enabled then OSBRiDGE 5XLi/5GXi device will send 3 ICMP Echo Requests to the
configured IP address, each in 3 minutes interval. If there is no single ICMP Echo Reply to any of
these requests, then the device will reboot itself.
The device has also independent hardware watchdog built in, that checks for critical operational
parameters and reboots the device, should the system hang or become unstable. That watchdog
works all the time, regardless of the ping watchdog configuration.
Run Web Server on Port – Enter the port the build-in Web server should be configured to run
on.
Web Login Timeout – Enter the value the management Web session should be kept alive
without any action from the user.
Reset to Default Password – Password that is used to reset device to factory default settings
using OSReset software.
NTP Server – Configure IP address of the external NTP (Network Time Protocol) server
OSBRiDGE device will obtain current time from at startup time.
ETH Speed – LAN Port connection speed - available values are Auto (Auto Negotiation),
100Mbps FDX, 100Mbps HDX, 10Mbps FDX, 10Mbps HDX.
Last Good Config - If Enabled then device will keep copy of previously used configuration and
directly after reboot, if the built in watchdog triggers reset, will revert back to that configuration.

4. IP Settings
Bridge Mode
Device IP – Enter device IP address here.
Subnet Mask – Enter network subnet mask here.
Default Gateway – IP address of a router where traffic going outside of the local network will
be forwarded.

Router Mode / NAT Router Mode
Wired Interface IP – Enter IP address of the wired interface here.
Wired Interface Mask – Enter wired network subnet mask here.

Wireless Interface Mask – Enter wireless network subnet mask here.
Default Gateway – IP address of a router where traffic not destined for defined routes / local
routes will be forwarded.
Defined Routes – This table displays currently defined static routes. To delete a route select
"Delete" checkbox and press Submit on the bottom of the page. Please note that it is not
possible to delete first two entries – direct routes to local interfaces.
Add Route:
Direct – Wired/Wireless - When router has two or more IP subnets directly attached to its
different interfaces, it can route IP packets between those subnets using a direct route. A direct
route consists of an IP Address which specifies the basic IP address to route, a Subnet Mask
which defines the class of IP addresses that will be routed, and an interface which specifies
where the IP subnet is attached. When an IP packet addressed to a system on the directly
routed subnet arrives at the router, the router will send it directly to the target machine on the
interface specified. When entering direct route use 0.0.0.0 as Gateway.
Indirect - When router needs to send IP packets between IP subnets which are not directly
connected to one of its interfaces, it must have an indirect route for sending those packets. An
indirect route consists of an IP Address which specifies the basic IP address to route, a Subnet
Mask which defines the class of IP addresses that will be routed and a Gateway that will relay
the IP packet. When an IP packet addressed to a system on the indirectly routed subnet arrives
at the router, the router will route it over to the specified Gatway to be routed further.

5. Advanced Settings
Fragmentation Threshold – Enter the size at which the packets will be fragmented.
RTS/CTS Threshold – Enter the minimum packet size to require RTS (Request To Send)
handshaking limiting on-the air collisions. For packets smaller than this threshold, a RTS is not

the RTS/CTS handshaking is established. This value should be only changed while operating as
an Access Point Client.
Distance to the Access Point – Configure distance between OSBRiDGE 5XLi/5GXi device and
the Access Point it is connecting to.
Tx Power - By default, the OSBRiDGE 5XLi/5GXi transmits data at the maximum output power
