--- Comment #8 from Jesse Allen the3dfxdude@gmail.com 2007-10-19 08:13:28 --- These are the instructions I wrote for D2 for proper /etc/hosts. Make sure you follow them exactly because I found when you don't you will have problems.
1. Have a valid internet addressible IP address for internet play or proper NAT forwarding. 2. Have a hostname other than localhost. 3. In /etc/hosts, have a valid hostname of your computer listed with your current IP address you want to use and do not have your hostname listed with 127.0.0.1. Do not have "localhost 127.0.0.1" listed first either.
