OSBRiDGE 3GN Configuration Guide

OSBRiDGE 3GN is a high performance 2.4GHz MiMO outdoor/industrial access point, designed to provide secure and reliable internet access anywhere through cellular 2G/3G backhaul technologies such as GSM and UMTS, or traditional wired backhaul such as xDSL or Cable.

There are two hardware versions of this device:

OSBRiDGE 3GN - is a MiMO Access Point with built in GSM/HSDPA modem. It can operate as a wireless and wired gateway for GSM internet access or as a simple MiMO Access Point bridging data traffic between wireless and it's both wired interfaces.

OSBRiDGE 3NR - is a MiMO Access Point/Repeater. It can operate as a simple MiMO Access Point bridging data traffic between wireless and it's both wired interfaces. It can also operate as a wireless repeater for OSBRiDGE 3GN or another OSBRiDGE 3NR, effectively increasing Wireless LAN coverage.

Hardware Setup.

Ports and connectors:

1 – Detachable UMTS/GSM antenna. This antenna port uses straight SMA connector which you can use to replace included antenna with higher gain, external GSM/UMTS antenna. Using external antenna is specificaly suggested when you are going to use OSBRiDGE 3GN in a car or remote location, where cellular coverage may not be the best. This antenna connector is available on OSBRiDGE 3GN only.
2 – WiFi MiMo Antenna.
3 – Ethernet Port 2.
4 - GSM SIM card socket. This socket is available on OSBRiDGE 3GN only.
5 - Ethernet Port 1. This port provides passive PoE (Power over Ethernet) support, DC Power Range: 9-18 Volt/1.5A.
6 - WiFi MiMo Antenna.
7 - DC Connector for Power Adapter (9-18V/1.5A, DC 2.1 mm).

Initial software setup and configuration.

Please note that after changing device parameters and pressing submit button, new settings will only be saved when you press "Apply Changes" button at the right bottom of the configuration page. You also need to reboot the device for the device to start with new settings.

System Information


System information tab shows information about system hardware and operational parameters:

Device Information:

Device Type – Device type you are logged into.
MAC Address – Device MAC address.
Firmware Version – Current firmware version.
Hardware Revision – Device Hardware version.
Regulatory Domain – Currently configured regulatory domain.

System Information

Device Name - System Name for easy identification of the device.
Uptime – How long the device has been up and running since last reboot.
System Load – Shows system load - Device processor utilization level.

IP 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.
Using default configuration both ethernet interfaces of OSBRiDGE 3GN or OSBRiDGE 3NR and wireless lan interface are bridged into one L2 network.

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 GSM gateway (OSBRiDGE 3GN) or any configured ethernet interface (OSBRiDGE 3NR). 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.

Watchdog – Disabled or Enabled, depending on current Watchdog configuration.

Wireless WAN Information
(OSBRiDGE 3GN only)

Device Name - This is the system name for easy identification of the OSBRiDGE device.

IP Mode
Bridge - In Bridge mode all device interfaces (ethernet 1, ethernet 2 and wireless LAN) are bridged together and all layer-2 traffic is forwarded between them..
Router - In Router mode all traffic is routed between interfaces according to the device routing table.
Gateway (NAT Router) – This is the default mode that provides internet access through UMTS/GSM interface (OSBRiDGE 3GN only) to all client devices connected to both ethernet and wireless LAN interfaces. In this mode both ethernet interfaces and wireless LAN interface are bridged together to operate in one Layer-2 network.
It is also possible to configure any other interface (Ethernet 1, Ethernet 2, Wireless LAN) to act as a network gateway interface and then all traffic going out of the access point is masqueraded and sent over that interface.

Wireless WAN Interface

Enabled - By selecting this box you can enable or disable Wireless WAN interface.

Please note that regardless of this configuration box Wireless WAN can be active only in Gateway (NAT Router) mode. Wireless WAN is disabled when device operates in either Bridge or Router mode.

Service Type - Here you can select which GSM service type should be used for operation. Available choices are: 3G Preferred, 3G Only or GPRS/Edge only. Please note that some GSM/UMTS networks doesn't allow manual service type selection and so the network itself will automaticaly select service type and override this setting.

IP Settings


Wired Interface IP 1 – Enter IP address of the first wired (Ethernet 1) interface here.
Wired Interface Mask 1 – Enter first wired (Ethernet 1) network subnet mask here.
Wired Interface IP 2 – Enter IP address of the second wired (Ethernet 2) interface here.
Wired Interface Mask 2 – Enter second wired (Ethernet 1) network subnet mask here.
Wireless Interface IP – Enter IP address of the wireless interface 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.

In Bridge mode all interfaces (Ethernet 1, Ethernet 2 and Wireless LAN) are bridged together and Wired Interface 1 IP Address and Subnet Mask are assigned as the bridge IP address.

Resetting device to default settings.

In order to reset OSBRiDGE device to factory default settings you need to use OSReset software available for download at http://www.osbridge.com/?q=en/software

OSReset will locate any compatible OSBRiDGE device regardless of its IP address located on the same physical subnetwork with the computer it is running on.

After selecting the device you want to reset enter "Reset to Default Password" in the Password: field and press button.

If you have changed Reset to Default Password to one you no longer remember then please email us at support@osbridge.com stating device type and MAC Address and we will provide you one time, generated password that will let you reset the device to factory default settings.
