Configuring your firewall

Whenever you can, you should host games without proxy. This is because disconnections cause huge sync problems with proxy servers.

The Java Blood Bowl client uses the ports 8080 for play and 8085 for spectators by default. You need to configure your firewall (if you're connected to the Internet these days, you do need one!), either a software one running on your computer, or a hardware one on your router, to 'port forward' these ports to your IP.

Linux - iptables

• Log as superuser su - (you need to know your root password for this)
  
• Edit your iptables config file /etc/sysconfig/iptables
  
• Add following lines to it:
  

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8086 -j ACCEPT

• After that you can restart your linux firewall with command /etc/init.d/iptables restart
  
• After you have done this one time, your system will automaticly open ports 8080 and 8086 every time it starts.
