I have installed the pi-hole app on my umbrel. This works great and blocks all sorts of ads when I configure my DNS to point to my umbrel’s private IP.
However, this only works when I am on my home network. When I go elsewhere, DNS does not resolve at all, since the internal IP address of the pihole is unreachable.
When I attempt to configure my network’s public IP as my DNS server, that does not work either (presumably because of network firewall / router configuration - I use whatever came out-of-the-box with Eero).
Is there a recommended way to use pi-hole while away from a home network?
