Why aren't my static routes working?

Hi allNeed some help with setting up static routes to block forced DNS lookups on several devices on my network (Chromecast, PS3) so that I can use Global mode with them. I will admit to not really knowing how this works and just following serveral online guides that tell you how to do this.This is what the applicable page in my router settings looks like:This does not seem to have worked, when I ping the DNS servers I still get a response:and the devices in question still aren't able to use global mode.Using an Orcon genius lite.Have tried using a different gateway IPThanks for your help
