Here is the case. Recently I tried playing online on Resident Evil 5 and Borderlands. I can't host an online game in which my friends could join. I don't have a problem connecting to Playstation Network itself. I can message and add friend, download demos etc. But its very weird connecting through the game gives me errors.
So I did some research and it told me to fix certain settings on my router and PS3. I manually created the connection to my router + modem and I successfully connected. On my router, I set DMZ Host for PS3, forwarded ALL Ports for PSN and Enabled uPnP.
But on my PS3 when I do the connection test I get the following:
Nat type 2
uPnP: Not Available
I have DSL connection running through Verizon, my modem + router is Westell 7500.
Can some one please help me with my problem?
