dark_cz 0 Posted September 21, 2018 Hi, which ports are needed and why? We are DDOSed all the time and I am trying to configure firewall, but when i use ports for arma3 then for some players server is not visible... Do DayZ server using different schema? Arma 3: 2302 UDP (gameport + VON) 2303 UDP (STEAM query port) 2304 UDP (STEAM master port) 2305 UDP (VON reserved port but not used atm.) 2306 UDP (BattlEye traffic port) so open ports 2302-2306 Share this post Link to post Share on other sites
SmashT 10907 Posted September 22, 2018 (edited) Open port 27016 if you want the server to show in server browser. Edited September 24, 2018 by smasht Share this post Link to post Share on other sites
