I been having so many errors in the past that i could have open a zoo.. The first thing you have to do is to look at this so you know what ports you need to open (xbox360 or xbox one or psx3 or psx4) https://www.bungie.net/en/Help/Article/11931 when you know the ports go to the link with the youtube video and do what he does... I have done it myself and it seems to work. Before i just used upnp and thought it would do the job but it dident,so i tried to port forward in the router and it works for me... PS: Remember to turn of upnp when you port forward..(in your router) PS:When you set your new ip adress just changes the last 2 digi on your xbox or psx( F.eks 198.168.900 then it goes like this 198.168.920 )
