hi im not going to lie I'm pritty useless with tech , I'm trying to get my nat type from strict to open and resolve my double nat issue , I've got a 4g ee sim. I can play online fine with random people but I can not play with my specific friends , it's quiet annoying 

I'm.not sure if it's just an issue with ee and having private ip addresses or something along those lines 

I read switching to three network could solve this . 

any help is appreciated 

thanks in advance
