how to setup a bridge with 2 NICs and few virtual machines
- by Bond
Here is my situation.
I have a server with 2 NICs.
I have installed virtual box and I have created a few Guest Operating Systems on it.
I want these Virtual Machines to be using a bridge.NIC2 would be used to setup this bridge and NIC1 would be connected to corporate network.I am not clear with how should I go on doing this.
/etc/network/interfaces is the file
which I am trying to modify etc.
My approach is following
1) Define a configuration file /etc/network/interfaces
2) Create IPTABLES as how NIC1 will forward the packets to Bridge on NIC2
Now comes the problem I do not understand what is the meaning of following lines in the configuration file
auto lo
iface lo inet loopback
# The primary network interface
auto eth2
iface eth2 inet manual
auto br0
iface br0 inet static
address 192.168.1.14
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.10
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 192.168.13.2
dns-search myserver.net
bridge_ports eth2
bridge_fd 9
bridge_hello 2
bridge_maxage 12
bridge_stp off
So any pointers to what should be the entries of /etc/network/interfaces file.
So that I understand which parameter is to be used when and where that would help me.
