If another person downloads this without reading the description... and asks me the same question I answer here, I'm going to kill a small animal.
In order to host a server that others can see, make sure you open ports 9100-9105 for UDP on your local router firewall.
Our community has hosted a new master server for Operation Flashpoint: Dragon Rising. Unzip these two files into your root Dragon Rising directory, and browse other player servers in the LAN browse section in multiplayer.
If you like this modification, please consider making a donation, or becoming a supporter here. We need to pay monthly bills to keep the master server active, and your support helps us do that.
Operation Flashpoint: Dragon Rising's servers are NOT dedicated. Every server you see is hosted by a PLAYER. This means that if you connect to games from Australia, and you're in Canada... you're going to have a bad time. The dedicated server files were never released for this game... in fact some of us think they were never made at all. This means you should try to play on servers within your local area... with low ping. If you don't, you might just ruin the experience of both yourself... and everyone else in the game. Private matches will probably help avoid this.
If you have any issues, make sure you report them HERE. Keep in mind Dragon Rising is no longer supported... which means we cannot always guarantee a fix. However we will try our best, and hopefully others with experience in the game will watch these forums.

What's New in Version 1.0.1 See changelog
This includes the executable that makes your game suck less. This isn't required for the master server to work, but the modified .exe gives you higher video resolution options, and overall better functionality. Pretty much necessary for a normal Dragon Rising experience.
