Explore a rooted option

On rooted devices there might not be the need for a dummy VPN. Using either iptables or by adding a route on the device traffic could be redirected to Nebulo which could then forward it as it does now anyways.

Pros/Cons:

IpTables:

• Pro: easy and fast to use, can target ports directly (allowing a forward of *:53 instead of host:* like it is currently)
• Con: Only works for IPv4 (no ip6tables equivalent)
• Con: Without using the VPN the dns server can't be set for all apps
• Con: Without a precise rule packets sent by Nebulo might be intercepted as well

Route:

• Con: Unsure whether all devices support it
• Con: Without a precise route packets sent by Nebulo might be intercepted as well (no way to exclude Nebulo from routing)
• Pro: Works with IPv6
