How to use the BroadBand Adapter (BBA)

This section will explain how to install and configure the software necessary for BBA use.

Windows

---

1. Install OpenVPN TAP Adapter V9, included in the OpenVPN installer: OpenVPN download page
2. Go to start menu. Click TAP-Windows and then click Utilities. Right click Add a new TAP virtual ethernet adapter and run it as administrator. It will complete in a few seconds.
3. In Control Panel\Network and Sharing Center\Change adapter settings, select the TAP device and the adapter you use to connect to the internet.
4. Right-click and select "Bridge Connections".

Linux

---

Install OpenVPN from your distribution package manager, then run the following commands (as root) to create the virtual interface and bridge it to your physical Ethernet adapter:

openvpn --mktun --dev Dolphin --dev-type tap
brctl addbr br0
brctl addif br0 Dolphin
brctl addif br0 eth0    # or whatever your network interface is
ip l set Dolphin up
ip l set Dolphin promisc on

You'll also need to change your network settings to configure IP/gateway on br0 instead of your usual adapter. Linux doesn't support adding a wireless interface to a bridge as of July 2012 so you need a wired NIC for that to work.

Config -> Gamecube -> SP1, select BBA.

Now you may play any games which use the BBA.
