You will nee to run another ArenaDaemon GameDaemon make a copy of ArenaDaemon01 folder and rename it to DungeonDaemon01.
Now you will need to make some changes on the file D:\service\DungeonDaemon01\bin\gamed.config.xml
Change ArenaDaemon01 to DungeonDaemon01 where it will be the new log folder.
<!-- ==== path ==== -->
<!-- [REQ] full root path -->
<option name='root-path' value='D:\Service\ArenaDaemon01\'/>
<!-- [REQ] full log path -->
<option name='log-path' value='D:\log\ArenaDaemon01\'/>
<!-- [REQ] full data path -->
<option name='data-path' value='D:\Service\ArenaDaemon01\data\GameData_GARENA.zip'/>
change 7801 to 7802 it will be a new cluster.
<option name='arena-id' value='7801'/>
change 11900 to 12900 or any other free port.
<option name='public-port' value='11900'/>
change 21900 to 22900 or any other free port.
<option name='internal-port' value='21900'/>
change 41900 to 44900 or any other free port.
<option name='builder-port' value='41900'/>
change 21902 to 22902 or any other free port.
<option name='managementd-port' value='21902'/>
to enable the chat change no to yes.
<option name='chatting-server-enable' value='no'/>
Now you will need to change the following config files.
D:\service\RankingDaemon\config\game-list.config.xml
add a new line where 192.168.1.1 is your Lan IP.
<game service-type='2' id='17802' ip-address='192.168.1.1' internal-port='22900'/>
D:\service\AchievementDaemon\config\achievementd-iplist.xml
add a new line where 192.168.1.1 is your Lan IP and the id is the new cluster + 10000.
<cluster ip='192.168.1.1' cluster-id='17802'/>
D:\service\ArenaLobby\config\arena-lobby-iplist.xml
add a new line where 192.168.1.1 is your Lan IP and the id is the new cluster.
<daemon type='arenad' ip='192.168.1.1' id='7802'/>
D:\service\ArenaLobby\config\arena-lobby-arenalist.xml
uncomment the line.
<arena id='7802' max-pc='8000' service-enable='y' attraction='dungeon'/>
Now on SQL database LobbyDB table GameWorldCluster you can manualy create a new line and insert the values "7802" "192.168.200.100" "12100" "7000" "5000" "192.168.200.100" "22902" or run this query.
INSERT INTO [dbo].[GameWorldCluster]([WorldClusterID],[GamePublicIPv4Address],[GamePublicPort],[MaxPlayerCount],[MaxWaitingCount],[GameInternalIPv4Address],[GameInternalPort]) VALUES (7802, '192.168.200.100', 12100, 7000, 5000, '192.168.200.100', 22902);
Now you can access Cross-server dungeon(f8)!
