Hi, I have just set up my router, which is 15.05.1.
After I plugged in the cable and connected my device to the router, I found out that I can access Internet, such as Google or something, but I cannot access some of our school's website.

I tried to ping our school website on the router, which is fine. However, when it comes to my devices, it did not work out.
Any help?

Update:
Discard upstream RFC1918 responses solves the problem.
