Hello Fellow Gamer,
Thank you for contacting Electronic Arts.
I do apologize for the issues you have been experiencing with The Sims 3. As a gamer myself, I can understand how frustrating this issue can be. I have been assigned to your issue, and would be happy to assist you in this matter.
According to your trace results, I would suggest opening the Online Ports necessary to play this title on your router.
The ports you will need to open are below:
UDP Ports: 53, 80, 88, 3074, 3658, 6000, 9555
TCP Port: 53, 80, 88, 443, 3074, 13505, 31400-31499
We recommend contacting your Internet Service Provider or Router/Modem manufacturer for information on how to open ports, or make adjustments to your home network.
