Hi people.
I am running pihole under podman and its dedicated system account on my NAS. Now, from the NAS, I get a connection refused on ip.of.the.nas:53 but everywhere else in my network, pihole works perfectly.
To run pihole as a rootless container, i made it listen on 1053 and I have a firewall redirection from 53 to 1053 for both udp and tcp.
Any pointer to where (and how) I can debug this ?
Edit: Small precision about my current setup : ISP router (so I can’t really do anything on it) and NAS running opensuse leap
Do you have any idea on how to do it ? Knowing that I am on opensuse
Well, on linux I’d use systemd’s resolved which would listen on localhost:53 (it would also point resolv.conf there) and then set resolved’s uplink server to your custom port. I don’t have the exact config in mind but it seems to support custom uplink ports(“expects IPv4 or IPv6 address specifications of DNS servers […] optionally take a port number separated with “:”[…]”)
