Configuring a static IP address bridge

If your network configuration is not controlled by a DHCP server, perform this task to configure a static IP address bridge.

1. (If required) To retrieve the IP address and the netmask, enter ifconfig interface_name.
2. Enter ifconfig -a to verify that the Ethernet interface is up.
   

   user@ubuntu:~$ ifconfig -a

3. Enter the ping command—specifying a known URL—to verify that you have internet connectivity.
   

   user@ubuntu:~$ ping example.com

4. Install bridge-utils, using the following commands:
   

   user@ubuntu:~$ sudo apt-get update
   user@ubuntu:~$ sudo apt-get install bridge-utils

5. Enter sudo vi /etc/network/interface to modify the following interfaces example with the values you retrieved, replace "eth0" with the actual server external interface, and replace all other < > with your values.
   

   auto lo
   iface lo inet loopback
   
   auto eth0
   iface eth0 inet static
   address 0.0.0.0
   
   auto br0
   iface br0 inet static
   address <ip-address>
   netmask <net-mask>
   gateway <gateway-ip-address>
   dns-nameserver <dns-nameservers> 
   dns-search <search-domains>
   bridge_ports <eth0>
   bridge_stp off
   bridge_fd 0
   bridge_maxwait 0

6. Save and close the file.
7. Reboot the server.
   

   user@ubuntu:~$ sudo reboot
