Re: Bridge

[Justin Brown <justin brown fandingo org>]

Florent,

If I understand you correctly, this should be easy. You will need to
substitute id, uuid, and mac-address fields as necessary.

/etc/NetworkManager/system-connections/eth0.ini
[connection]
id=eth0
uuid=7974cee9-c454-4d0f-93b1-37f93de2ae92
type=802-3-ethernet
master=71abc14f-fd97-4d62-9a2b-6d07e8a2801c
slave-type=bridge


[802-3-ethernet]
mac-address=00:1e:4f:fc:3e:02

[ipv4]
method=ignore

[ipv6]
method=ignore
==================
/etc/NetworkManager/system-connections/br0.ini
[connection]
id=br0
uuid=71abc14f-fd97-4d62-9a2b-6d07e8a2801c

type=bridge
autoconnect=true

[bridge]
interface-name=br0

[ipv4]
method=manual
dns=192.168.25.100;192.168.25.101
addresses1=192.168.25.10;192.168.25.1;
===================
/etc/NetworkManager/NetworkManager.conf
[main]
plugins=keyfile

chmod 600 those ini files and reboot.

sysctl -w net.ipv4.ip_forward=1


Attach your guests to br0, and they will be able to communicate
directly with your laptop's network.
