General Setup
By default a 3.X firmware is set to DHCP. To find the IP which the beronet device received the bfdetect tool can be used. If no DHCPserver is available the beronet devices falls back to its default IP address: 10.0.0.2
beroNet VoIP Card Setup
The beroNet VoIP Card is build in a special way, so that it appears as a network card in the server where it is installed (e.g in the beroNet Appliance). The following picture shows how the card works in the server with the mainboard.
As you can see the card creates a LAN inside of the server. There are 3 major options to handle the network topology:
1. Network Bridge (recommended) 2. IP Forwarding with different LANs 3. different LANs without IP Forwarding
The IP Forwarding and the non-Forwarding Scnarios are only useful in special situations, where the beroNet VoIP Gateway part of the Card should not receive an IP of the main LAN and thus be invisible to it. In most cases the network bridge setup is recommended.
beroNet VoIP Cards Bridge Setup
In the following Chapters we will describe how you can configure a Network Brigde under Linux and Windows based systems.
Linux Network Bridge
You can setup the Network Bridge under Linux with the "brctl" utility. This utility is provided by the "bridge-utils" package on debian based systems (like Ubuntu). As mentioned above the berofix PCI/PCIe cards use MAC Addresses beginning with D8:DF:0D or 00:50:C2, so you can again use the "ifconfig -a" command to identify berofix PCI/PCIe cards:
beropbx:#ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:0C:6E:D3:86:C6 this is standard NIC
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:797562 errors:0 dropped:0 overruns:0 frame:0
TX packets:35206 errors:20 dropped:0 overruns:0 carrier:20
collisions:7447 txqueuelen:1000
RX bytes:141351732 (134.8 MiB) TX bytes:19431622 (18.5 MiB)
Interrupt:11 Base address:0xc000
eth1 Link encap:Ethernet HWaddr 00:50:C2:83:D0:01 this is our berofix PCI card as you can see on the MAC-Address
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:35124 errors:0 dropped:0 overruns:0 frame:0
TX packets:276362 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:20636164 (19.6 MiB) TX bytes:28931756 (27.5 MiB)
Interrupt:11 Base address:0xa000
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:9 errors:0 dropped:0 overruns:0 frame:0
TX packets:9 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:720 (720.0 b) TX bytes:720 (720.0 b)
In this example eth1 is the berofix PCI card and eth0 is our default network interface which is connected to our LAN. We want to assign the IP Address 192.168.0.2 to our LAN interface and the IP Address 192.168.0.3 to our berofix device. After we have setup the Network Bridge we want to access the berofix PCI card from all machines in our LAN, which are located in our network 192.168.0.1-254. To establish the Network Bridge, you have to use a few commands like described in the following example:
berofix:# ifconfig eth0 0.0.0.0 up berofix:# ifconfig eth1 0.0.0.0 up berofix:# brctl addbr br0 berofix:# brctl addif br0 eth0 berofix:# brctl addif br0 eth1 berofix:# ifconfig br0 192.168.0.3 up
These commands will first remove the IP-Addresses from the network devices and then will create the Network Bridge and add your standard network card (eth0) as well as the berofix PCI card (eth1) to this newly created Network Bridge (br0). In the example above we applied the 192.168.0.3 to the Network Bridge. The default IP settings of the berofix PCI/PCIe cards are 10.0.0.2 netmask 255.0.0.0. To make the berofix reachable from our LAN the IP-Address of the berofix device has to be changed. This can be done using the bfdetect tool (which is described in the next chapter) or through the webinterface of the berofix device. So we assume the berofix IP Address is changed to 192.168.0.3 with Netmask 255.255.255.0 . If everything was setup as it should, you should be able to reach the berofix device(192.168.0.3) from any machine in your Lan. Unfortunately this described way is not persistent and will be deleted after rebooting the machine.
To setup this Network Bridge in a persistent way, you can modify your "/etc/network/interfaces" file on debian based systems (like ubuntu):
auto lo iface lo inet loopback
auto br0 iface br0 inet static address 192.168.0.2 netmask 255.255.255.0 gateway 192.168.0.1 bridge_ports eth0 eth1
After that you have to restart your networking:
berofix:#/etc/init.d/networking restart
After everything is up and running, you should be able to reach the berofix device (192.168.0.3) from any machine in your LAN.
Windows network bridge
To use the Network Brigde under Windows based Systems (Windows SBS Versions don't seem to support Network Bridging) open "network connections" Window. As already seen in the chapter IP-Forwarding, you will see two Network controllers. Your standard Host Network Controller ("Local Area Network Connection 1") and the berofix Network Controller ("Local Area Network Connection 2"). To create the Network Bridge please mark both connections and click the right mouse button. The following context menu will appear:
Click on "Bridge connections" and a third Controller will appear, our Network Bridge:
As you might notice the Network Controllers don't have IP Address's any more. You can only assign an IP-Address to the Bridge Controller. By default the Bridge is in DHCP mode. If you please mark the Bridge, click the right mouse button, choose "Preferences" and configure an IP-Address. At that moment the Network Bridge is reachable throughout the LAN - you can also reach the berofix web-interface. For example:
Let's assume your LAN is 172.20.0.0/255.255.0.0, your bridge got an IP 172.20.5.194 and you configured berofix internal IP address to 172.20.70.11. Through the configured bridge, berofix is reachable from the whole network now, if your firewall is not blocking it!
bfdetect
The latest version of bfdetect can be found in the downloads page. It is used to discover the beroNet device IPaddresses of the local subnet. It can also be used to change the network settings of the beroNet device, e.g. to set it into DHCP or static IP mode.
NOTE: bfdetect can be disabled via preferences->network in the GUI, to avoid unwanted network setting changes from bfdetect users in the local subnet.
After changing the IP address or learning it, the Web GUI can be used to configure the gateway. Just point the IP in your favourite browser and you should see the login-screen.
