Setup the TecO WBridge
The TecO WBridge can be used in multiple application scenarios. Please use the tool setup_router to configure the WBridge for the different scenarios. This guidline should help you to choose the correct setup for your application.
direct Access via LAN (Mode 1)
This mode is very easy. You have to configure the LAN interface of your PC and your WBrigde with two different IP addresses that belong to the same network, that's all. You can also use the particle_tunnel to send the packets via TCP to the PC, but that's not neccessary.
direct Access via WLAN (Mode 2)
This mode is very similar to the first one. The only difference is, that the data will send ba WLAN and not LAN. Configuration is nearly the same, but you must also choose a WLAN-channel.
Access via LAN (Mode 3 and 4)
If you have already worked with the XBrigde, you should know this scenario. The WBridge is part of a local network and will broadcast the packets to the network. Mode 3 is the one you must use when the WBridge should receive its IP-address from a DHCP server, mode 4 if you want to configure it with a static IP address (please be sure that the IP-address and netmask are compatible with your LAN!).
If you don't want to broadcast the data via UDP in your local network but send them via TCP, please use mode 5 or 6.
Access from a second network (Mode 5 and 6)
If you want to send the particle data to another network (e.g. via DSL), you must send the data via TCP to a tunnel server. To configure the WBridge for TCP transfer, you need to know the IP-address from the tunnel server and the port it runs on. Please make sure that the tunnel_server is attainable from the second network (NAT, firewall, etc.)
Similar to the use in a local network, you can configure the WBridge via DHCP (mode 5) or with a static IP-address (mode 6).
Mesh network with access to a LAN (Mode 7-9)
There is also the possibility to build mesh networks with the WBridge to forward data. You always need a tunnel server when working with mesh networks, as OLSR only forwardy TCP packets.
There are three kinds of routers/WBridges that can be part of such a mesh network: The WBridge itself (red 1 in the drawing, mode 7 at the setup util), a router/WBridge that only forwards data vir OLSR but does not have it's own particle bridge (red 2 / mode 8) and a gateway to a local network (red 3 / mode 9).
Please note that a WBridge is always playing the role of a Router. So it's not neccessary to have routers/WBridges in mode 8 as a part of the mesh network.
Additional note for the Gateway: The gateway must be connected with the WAN port to the ethernet. The IP-address you enter to setup_router must be the IP address that matches with the overlay network.
pure mesh network (Mode7-8)
This scenario is very similar to the lust one, but there is no gateway needed as the PC with the tunnel_server is part of the mesh network.
