How To Block traffic from *.playstation.net on an Actiontec MI424 router (Verizon FIOS)
Info: When this rule is created and enforced on your router, all traffic to sites ending in .playstation.net will be completely blocked. This way you can still have internet/LAN access on your PS3 but only block traffic from sony domains. The following router is one currently being installed to clients of Verizon FIOS internet.
1. Log in to router: typically 192.168.1.1 with whatever your default username and password is.
2. After logging in go to the "Parental Control" tab.
3. In Step 1 of this screen select the correct IP you have assigned to your PS3 and hit Add.
4. In Step 2 of this screen check "Block the following Websites and Embedded Keywords within a Website" so it is enabled. Type in playstation.net in the website box. As an alternate you can even type in playstation in the "Embedded keyword within a Website:" box. Hit ADD. Under the schedule section check each one of the days of the week so they are all selected. Keep "Rule will be Active at the Scheduled Time" selected, Keep the start times default at 1am.
5. Create a rule name and description (doesnt matter for reference only)
6. Hit Apply to enforce the newly created rule.
To Test if correct: Boot up PS3 and go to the "Whats New" tab. If you see a bunch of boxes with no content/logos and if clicked on if you get a (80028E02) error, then the rule is working correctly. To test to make sure all other traffice besides this is working correctly, open up the PS3 browser and go to google.com or even psxstore.com.
It should load but once you reach a point where you are hitting the download button on something on there, you should get an error screen with a message from your router saying access denied to: and give the full URL of where it was trying to reach out to.
Last but not least I would love to get feedback from anyone who knows more about blocking sonys traffic than what I have found thus far.
Thanks Drizzt for the info and thanks to EVERYONE else who has contributed to the scene. Hopefully things pick up soon!
