If you save your settings and power cycle your router and devices you should be able to see on your devices under DNS the addresses of your Pi-Hole's rather than the address of your router (which is what you would see if you used either of the other two locations to enter your Pi-Hole addresses. ![]() ![]() In this box we will specify the DNS servers. Network -> Interfaces -> LAN -> Advanced Settings -> DHCP-Options We do that in the interfaces section above. Instead, we want to use dnsmasq to advertise the DNS server addresses. If you were to force redirections in the firewall and use conditional forwarding on the Pi-Hole you will end up with millions of queries for reverse lookup which will eventually bring your pi-hole to it's knees. However, assigning the Pi-Hole addresses here will have the router forward DNS requests to the Pi-Hole rather than the devices. Alternatively, in Network -> Interfaces -> LAN -> general setup -> Use custom DNS servers. First, in the Network -> DHCP and DNS section under DNS forwardings. Redirect hard coded DNS entries to the Pi-Hole's to ensure blocking across all devices.įirst, there are a number of locations you can assign the Pi-Hole DNS addresses. Use conditional forwarding so the Pi-Hole's show the names of the devices on the network. Pass the DNS servers off to the devices rather than have the router forward to the Pi-Hole's. Have two Pi-Hole's working in tandem to make sure there is a fail-safe in case one goes down. I disabled IPv6 as my ISP does not support it. By default this should be installed but you can check for it in the system -> software -> installed packages section. The router is assigned the address 192.168.1.1ĭnsmasq installed on the router. I have used the synchronization scripts that you can find all over this sub to keep the blocklists, blacklists, whitelists, and regexlists all in sync. I hope this is helpful to anyone else running OpenWRT. I have been playing with setting sand have come up with the following things. If those tips are resolving the issue, and it is not occurring in any other channel on your device as you mentioned, you'll want to continue following up with the channel provider for more help.OpenWRT is pretty powerful but it can be a bit confusing to set up. Notably, try removing the channel from your Roku home screen, restart your device, then try adding the channel back once more. Our recommendations for troubleshooting channel-specific issues are detailed here. You'll need to reach out to Amazon support to report the issue, discuss further investigation of your specific issue in their channel, and request additional updates on the status of the issue. We'll help pass along the feedback to a channel (app) provider, however, channel specific issues often require a channel-side update in order to be resolved. If you are experiencing an issue that only affects a specific channel, the channel provider will need to investigate the issue occurring within their channel to help work toward a potential resolution.
