The use of Bridge Mode will allow you to take the IP address that arrives from the mobile operator network and funnel it straight down into the first device that sits behind your Dovado router. This means that the Dovado router will no longer be serving as a conventional NAT router, but as an advanced USB-to-Ethernet converter. If your operator only hands out 1 IP address to your subscription, then only one device can be connected behind the router at a time; this could be a video camera, server or even an existing router/firewall that would benefit from a mobile broadband connection. For those of you who already have routers at home and are missing a mobile broadband connection out of it, a Dovado router operating in Bridge Mode will solve this for you! For example, if your office already has invested in a rather expensive router/firewall, a Dovado router operating in Bridge Mode would easily serve as a substitute for a fast fiber connection. The Dovado router would not interfere with the setup of the existing network by imposing an additional layer of NAT (private network) ahead of it. The Dovado router would merely make sure that it is connected at all times to the mobile network, and providing the IP address to the first recipient behind it.
Features that will not work when operating in Bridge Mode:
• Traffic counter
• DHCP server
• Connection Tracker
• Fail-over between WAN & USB and vice versa (Bridge Mode is strictly for USB).
• E-mail notifications
• WAN port traffic
• Home Automation
• Dynamic DNS
Features that will still work in Bridge Mode:
• Ethernet LAN (depending on number of ports vs number of received IP addresses from mobile operator)
• WLAN (Same as LAN; however if you have no need for WLAN in this setup, then disable it!)
• NTP Clock (synchronizes upon initial connection, right before switch to Bridge Mode)
• A low level connection watchdog that monitors the modem status and connection with the mobile network.
• Ability to log into the router's default LAN IP address for admin purposes (e.g. http://192.168.0.1)
• SMS Inbox / SMS Remote Control / SMS Notifications
To alter your router into a bridge, go to the INTERNET -> INTERNET CONNECTION page within the web interface, and select either of two Bridge Modes. If you are not planning on using any specific WLAN client, then use the "Bridging USB with LAN" option in order to avoid the risk of any unwanted connections by other WLAN devices. Save the new settings and restart the Dovado router after having connected it through LAN or WLAN to the existing device you want to bridge the connection to. After a couple of minutes the Dovado router should connect and the device behind it should be able to access the connection using the public IP. While in bridge mode, the router will indicate "CONNECTION: BRIDGE" if you log into the web interface.
Advice: Do not switch devices that are connected to the LAN port while operating in Bridge Mode. If you must do so, then make sure to restart the Dovado router first. The reason is because the IP address that derives from the mobile network shall be paired with the first hardware (MAC) address it comes into contact with. Introducing a new device on the Dovado LAN port will not allow you to pair that device with the original IP address assigned for that bridge. Therefore, a new bridge needs to be built, and this is done by restarting the Dovado router.
