BBA on Ubuntu 16.04 (LAN Mode)

[NaWer]

Hi folks,

I've tried to play Kirby Air Race on LAN (not NetPlay) and can't have it working...

I don't understand what I really need to do.

Code:

openvpn --mktun --dev Dolphin0 --dev-type tap --user     $(whoami) --group $(whoami)
brctl addbr br0
brctl addif br0 Dolphin0
brctl addif br0 enp1s0
ip l set Dolphin0 up
ip l set br0 up
ip l set Dolphin0 promisc on

When I run those commands, I can't even ping others computers...

After this failure, I've tried to create bridge with network-manager and name the bridge Dolphin0 :
http://ask.xmodulo.com/configure-linux-bridge-network-manager-ubuntu.html
It says :
"At this point, the bridge connection will automatically be activated"
But it doesn't and I don't know how to connect to this newly created bridge.


Any help will be appreciated
