[surviv0r1969]

anyone know of a straight forward guide to setting up an arma3 server on my pc?
thanks

check if you´re on a ds-lite tunnel first, it doesn´t work anymore if you do not have a ipv4 ip adress

This is easy though. Enable Steam tools, find the Arma server and install it.

contact me for more precisions.

Also you have these following steps:
1) find your server path
-> with the classic game you have all the files and so the server files too.
usually the path is:
C:\Program Files\steam\steamapps\common\ArmA 3\
!!! due to the spaces in the path [...\Program Files\...\ArmA 3\] you MUST use " before and at the end onf your path:
"C:\Program Files\steam\steamapps\common\ArmA 3\"

2) check your machine ressources:
-> CPU core without hyperthreading (intel core i5 has 2 cores; intel core i7 has 4 cores; AMD Ryzen 6 has 6 cores)
-> knowing hyperthreading capability of your machine. If you are using an old machine with cpu without hyperthreading capability don't use the argument -hyperthread in your batch command.
-> memory capability: arma3 servers used at least 1Go (1000Mo). You can use more but i advise you to not used the entire memory due to the swap works, slowdown your server

3) The game ressource path and maps
usually maps are in folder:
C:\Program Files\steam\steamapps\common\ArmA 3\MPmissions
the maps files are called as "bank" by Bohemia structure as"*.pbo" files.
These files can be open using bohemia tools

4) the server setup files:
You can use nothing by default, but your server will use the factories functionnalities.
To use a well strict vision to yours'server you must make a new folder at arma3 root and make news following files:
- basic.cfg
- config.cfg
you can use those Gamerfoo used[http//ftp]
Full link:
ftp:/gamerfoo:[e-mail]/Depot-ftp/Serveurs/ArmA3/conf/
(type truely: ftp:// --- ftp 2dots slash slash...)

5) security files:
in each mods you have files called : "server key files"
these files must be copied in the key folder:
C:\Program Files\steam\steamapps\common\ArmA 3\keys\

6) check the server hive.
Called so the server profile folder:
C:\Users\%USERNAME%\Documents\Arma 3 - Other Profiles\SERVER_FOLDER\

%USERNAME% is the windows variable for your current windows profile OR the server windows profile if you are doing a true dedicated server.

check only this file:
server_name.Arma3Profile

You will be able to force some GUI informations for clients (crossaim, radar, thirdview, and much more)

If you have a persistent server, the classical memory is the server_name.vars.Arma3Profile.
If you delete this file, the current game backup is over. But server memory is so complicated because a lot of different kind of file and it depend the commands in pbo files.

7) check your windows firewall and your anti virus firewall.
I advise you to authorize your program through windows and antivirus. Don't try to manage by port at this point.

8) check your router firewall => do port forwarding at this point.
call me for more precisions because every routers are differents.

9) do your batch command line and launch it
call me to have more help at this point.

Get time to check every arguments "...path..." -argument_1 -argument_2 -...
if you have any question contact me or go to Bohemia wiki[community.bistudio.com]

batch command line exemple:
"C:\Steam\steamapps\common\Arma 3 Server\arma3server_x64.exe" -malloc=system -cpucount=2 -maxMem=1000 -cfg=srv\basic.cfg -exThreads=1 -config=srv\gfoo-becti_0197.cfg -name=becti_0197 -port=2312 -loadMissionToMemory -bandWidthAlg=2 -autoInit -serverMod=C:\Steam\steamapps\common\Arma 3\!Workshop@CBA_A3;C:\Steam\steamapps\common\Arma 3\!Workshop@ace;C:\Steam\steamapps\common\Arma 3\!Workshop@CUP ACE3 Compatibility Addon - Terrains;C:\Steam\steamapps\common\Arma 3\!Workshop@CUP ACE3 Compatibility Addon - Vehicles;C:\Steam\steamapps\common\Arma 3\!Workshop@CUP ACE3 Compatibility Addon - Weapons;C:\Steam\steamapps\common\Arma 3\!Workshop@CUP Weapons;C:\Steam\steamapps\common\Arma 3\!Workshop@CUP Vehicles;C:\Steam\steamapps\common\Arma 3\!Workshop@CUP Units;C:\Steam\steamapps\common\Arma 3\!Workshop@CUP Terrains - Core;C:\Steam\steamapps\common\Arma 3\!Workshop@CUP Terrains - Maps;C:\Steam\steamapps\common\Arma 3\!Workshop@CUP Terrains - CWA;

Good work mate ;)

This is a well thought out guide: https://community.bistudio.com/wiki/Arma_3:_Dedicated_Server

But you can also host multiplayer games from within the game client multiplayer menu. Just make sure you have ports forwarded to your computer. (explained in link above)
