If you don’t like Sony spying on you and stealing your personal data, or you are just afraid of an accidental firmware upgrade ruining your jailbreak and rendering your precious console a cheap piece of junk, you have to block PSN access.
If you’re using a DD-WRT router, just login to the control panel, enter Services, add these lines to the DNS masquerading:
You don’t have to enable Local DNS, just save and reboot the router.
Now, even though the ping is ok, the browser can’t open playstation.net. As traceroute shows, the actual ip address resolved is localhost, meaning the device is connecting to itself.
C:\>tracert playstation.net Tracing route to playstation.net [127.0.0.1] over a maximum of 30 hops: 1 <1 ms <1 ms <1 ms MyPC [127.0.0.1] Trace complete.
If you don’t have a good router, you may register at any free online DNS service and block PSN access from there. On the console, enter Network Settings, chose Manual configuration and enter the DNS address given by the free service you registered at.
You console will still be online and accessible via netwrok, but the PSN will not be available.
