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
If the firewall was running on a router then you’d need to DNAT back to the same network from which they originated and that is (in general) quite a PITA to get running properly. My understanding is that the firewall doing port forwarding is running on the NAS. And we don’t have much information on what that ‘NAS’ even is, I tend to think devices like qnap or synology when talking on NAS-boxes, but that might as well be a full linux-system just running CIFS/NFS/whatever.
OP could obviously use his router as a DNS server for the network and set upstream DNS server for the router to pihole, but that’s a whole different scenario.
For now my NAS it not really running anything (I want to have proper DNS/IDM before starting any other service and for storage I think I may go with owncloud ocis or nextcloud)
