It looks like that after rebooting the router after installing Adguard - everything is fine now.I have installed latest Voxel FW and decided to make a change this time before installing Adguard. I edited dnsmasq from Kamoj menu by adding port 5300, so that Adguard can listen on port 53. However now whenever I change upstream DNS, I need to reboot the router in order to see the changes implemented. Any reason or fix for that?
