Hi all,

How to configure the bridged network for VMs without router on the internal network

Remark:
In my old FTTH plan the ONT is with a built-in router but in the new FTTH plan the ONT is without a router

Internal network connection:
FTTH (new plan)
-> ONT (Optical Network Terminal)
-> 4 ports (for connecting computers)

⟫ ifconfig

Code: Select all

eth0      Link encap:Ethernet  HWaddr f0:79:59:65:2f:bb  
          inet addr:42.2.2.2  Bcast:42.2.2.255  Mask:255.255.255.0
          inet6 addr: fe80::b7ec:1609:53c6:bda8/64 Scope:Link

          collisions:0 txqueuelen:1000 
          RX bytes:8382 (8.3 KB)  TX bytes:14122 (14.1 KB)

          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:213 errors:0 dropped:0 overruns:0 frame:0

Bridged networking with router (old FTTH plan)

Host
/etc/network/interfaces

Code: Select all

auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet manual

# add bridge ports
auto br0
iface br0 inet static
        address         192.168.8.4
        dns-nameservers 218.xxx.xxx.xxx 219.xx.xx.xx
        network         192.168.8.0
        netmask         255.255.255.0
        broadcast       192.168.8.255
        gateway         192.168.8.1
        bridge_ports    eth0
        bridge_fd       9
        bridge_hello    2
        bridge_maxage   12
        bridge_stop     off

Whether replace
address 192.168.8.4 with

Code: Select all

address 42.2.2.2

replace
network 192.168.8.0 with

Code: Select all

network 42.2.2.0
