24.7 Production Series / Re: Local application (Prowlarr) can't connect after Opnsense router install
« on: October 30, 2024, 05:16:45 pm »
I fixed it by doing something so totally unrelated to OPNSense that I'm actually more confused than before.
In the docker compose file for PiHole, I had to map not only port 53 on the host to port 53 internally, but also the hosts IP address. In this case of course the host is my Raspberry Pi.
So the config line went from this:
"53:53/TCP"
"53:53/UDP"
To this:
"192.168.117.200:53:53/UDP"
"192.168.117.200:53:53/TCP"
I found this suggestion on an extremely obscure forum after working out that my containers DNS resolution wasn't working when the DNS server was set to the PiHole host IP but would work if I set it to something externally like 8.8.8.8.
The real head scratcher is why did this work without issue when the TP Link router was installed?
After hours of troubleshooting this is one question I'm happy to walk away from unanswered.
Thanks all!
