I have graphene running on a Pixel 8. I have a PFsense router with openVPN configured for remote access to my self hosted applications. openVPN is NOT configured to force my DNS servers for the clients and it is working well on my other devices. It is setup as a split tunnel so only traffic to my home IP addresses is routed through the VPN. I am using the openVPN connect app from the Aurora store, and I have disabled the always on and force VPN options in the graphene settings.
I am also using nextDNS to DNS filter/ block known tracking & ads domains. When I enable my openVPN connection it prevents my device from connecting to my private DNS servers, which keeps me from being able to browse the internet outside of my serviced on my home network. When I switch private DNS to "automatic" it resolves the issue.
I would like to be able to continue to use my private nextDNS server while connected to my home network. Am I missing a setting somewhere or is this a known issue?
