ok guys, it's pretty simple actually. here's what you need to do. To open port your PS3 connection, begin with;
1. Check ur PS3 IP address, boot ur PS3 and go to your
Network Settings > Settings & Connection Status List. here you need to remember the numbers as you'll need to type this numbers to your router later on.

2. Once you're done with that, open your router settings (by default, most of the router address is 192.168.0.1 or 192.168.1.1). Currently i'm using Dlink DI-524 (wireless router & modem). Depending on what kind of router you are using right now, different router provides different names of 'Port Forward', as for my kind of router it's called 'Virtual Server'. Here i've added 3 more connections to open my PS3 connection without any restriction. These are the PS3 ports;
QUOTE
What ports need to be opened for the PLAYSTATION(R)Network?
TCP: 80, 443, 5223
UDP: 3478, 3479
for voice chat, UDP: 3658

You can choose one of those ports given above. Save & reboot your router, you're done! Enjoy your blazing fast PS3 connection

i hope this will solve your ps3 connection problem.
