Eu nao percebo nada disto por isso agradecia um passo a passo detalhado de como abrir portas para jogar Ark, vi na internet a solucao para poder abrir o server mas preciso da vossa ajuda,  a solucao é 

"1.Start by logging in to your router. 2.Find your routers port forwarding section. 3.Put the IP address of your computer in the correct box in your router. 4.Then put the TCP and UDP ports for your game in the corresponding boxes in your router. The UDP ports are 27015,7777,7778 and the TCP port is 27020. (If you dont understand some steps just look for them on the internet.) Then you have to create a non dedicated server, and it will probably appear on the server list. If not, your friends have to start singleplayer session then press "Tab" to open the console and write "open your ip adress:7777" for example "open 11.222.333.444:7777""

como falei antes, nao percebo nada, ja tive ate na pagina de mapeamento de portas ipv4 mas nao sei o que colocar e onde o fazer... desde ja agradeço
