I'm new to Ubiquiti hardware and really any sort of networking beyond basic typical consumer router config and recently installed an Edgerouter Lite X on my network for routing purposes. I've basically left all configuration as default except for:
- Made my name server under settings the internal IP of my rasberry pi (w/ pi-hole)
- Made the DHCP DNS also the IP of my pi
What I'm seeing is that certain sites will fail to load with either an dns_probe_finished_nxdomain or a connection refused. If the nxdomain message, using other browsers or devices on the network often gets it to load, or just refreshing after waiting a few minutes. For the connection refused, it won't load no matter what I do. Github is an example of the latter, I can't load it on my network.
I'm expecting there's some simple firewall config at play here, but am not sure the best way to resolve. I've tried reverting above changes just to make sure it wasn't something w/ the pi config, but the same behavior happens.
Any ideas for what I've gotten wrong here?
