NETWORK SCHEME /
We expect a lot of teams this year.
Team network for team N is: 10.A.B.0/24, where A = 60 + N / 256, B = N % 256.If it seems difficult, just enter a team number
SET UP VIRTUAL MACHINES /
Import both images to VirtualBox: "File->Import Appliance...
Check router image settings. Go to: "Settings->Network->Adapter2". Make sure that it is bridged to your real, hardware network adapter. It is preferable to use Ethernet adapters for bridging rather than Wi-Fi adapters.
Check test image settings. Make sure that Adapter1 is bridged to your real network adapter.
Start both virtual machines. You will see some instructions on a logon screen.
Follow instructions on the logon screen and enter your team number to configure the network:
eth0 - this is your uplink. Address is obtained via dhcp by default. This interface is attached to NAT in VirtualBox, so make sure that you have an internet connection on your physical host;
eth1 - this is your internal interface. It should be automatically set to: 10.A.B.1.
eth0 - it should be automatically set to: 10.A.B.100 and gateway: 10.A.B.1.
You should use following network settings for your team's PCs during the game (or virtual machines setup):
IP = 10.A.B.128 - 10.A.B.255
Netmask = 255.255.255.0
Gateway = 10.A.B.1
DNS = 188.8.131.52
SET UP VPN CONNECTION /
Follow the instructions sent on your PoC email(if not, please send message to: email@example.com) to obtain your OpenVPN config.
Copy the config to /etc/openvpn/*.conf (for example to /etc/openvpn/ructfe.conf).
Restart OpenVPN on your router (/etc/init.d/openvpn restart).
Check network connectivity. You should be able to ping 10.C.B.1 from your router and testimage(C = 80 + N / 256, N is your team number).
Leave both images running. You can shut down your testimage when the game starts.
