My team and I are hosting a LAN-party this friday and we expect about 20 people to enter our Minecraft: Hunger Games contest.
The problem is that we have no firewall or router access, and all attendees will be on the same school network.
What is our best option for server setup? Do we rent one? Running the bukkit from my computer is impossible, I need to port forward to let people on the server. If I open my games to LAN, no one can connect because of firewall configuration.
Thanks in advance
