Hi, I had checked the option "Allow Sharing Nameserver Ips" in Tweak Settings, an two nameservers with the same IP. Now I want to disallow this option (unchecking it), but the change does not take effect, every time I enter Tweak Settings this option is checked. 1) How can I disallow this option? 2) How can I disallow an ilegal nameserver that is using this feature without authorization? Thanks for your help.
