Multiplayer won't work, so i called up my ISP Just Yesterday(Eircom in Ireland)
and told me to get some ports from Port forward and put the ports into my router.Also, They said to put my Firewall to low to change my NAT type to Type 2(it was Type 3).
I found the ports and they were:
Start Port: 3478
End Port: 3478
IP Address: My PS3'S IP Address (192.168.1.4, which was the IP Adress AT FIRST, Then a day later i had to change it to 192.168.1.2)
End Port: 4380
IP Address: same
IP Address: Same
My ZyXel Router Model No.: P-660HN-T1A_IPv6 (A Month or two before that it was ZyXEL P-660HW-T1v2)
When i entered these ports, My multiplayer worked until I turned off my PS3 and when I turned it back on next morning:
1) My Multiplayer didn't work.
2)My Internal IP Address changed to 192.168.1.2 and it's been staying like that.
3) when i login into my Router, 192.168.1.2 AND 192.168.1.4 showed up in my client list when I logged into my Router but the green light only showed up on 192.168.1.2, and again, it's been staying like that.
