I've recently purchased a NetDuma R3 and loving the geo-filter features so far. However, I'm really surprised at the lack of basic settings this router is missing. For example, when you go to DHCP settings, you can set the DHCP range, but you cannot define a custom DNS IP address.
Also, under the advanced LAN settings, there's only one toggle to enable IPv6. There isn't much for customization. For example, I'd like to set a static IP address for my DNS and not have the utilize my router as the DNS resolved for my devices.
Thanks!
