We have a customer who wants to utilize the RVS4000's Internet Access Policy to block social media sites such as Facebook and MySpace. Thier router is running firmware version 1.12.11. Now, the policy we have setup works, but only with Internet Explorer. Chrome, Opera and Firefox are still able to access forbidden domains. We've tested this out with another router running V1.2.10 with the same result. Any ideas or is this something that will need to be addressed with the next firmware update?
