I havent tried port forwarding yet. i have tried to connect to destiny servers and naughty dog's for UC4.
I get error code 33987-0 evertytime i try to connect to psn. As mentioned earlier when i switch to a different network and connect to psn and than again switch back to my original connection (the one i intend to play on) it remains connected. Occasionally after doing this i'm able to play online without any hitch but occassionally i'm not, which makes me wonder if its the ISP or router that i need to replace. But every time i go online i have to connect to psn in this method only.
When I use test connection I'm getting a NAT type 2 connection only. When i get the opportunity maybe I'll try to get a screenshot of connection results and post it here.
Thanks everyone for your solutions.Sorry for not being able to reply sooner
