I want to set up my RPI3 as the DNS on an Actiontec C3000A router. The interface is confusing to me. The nice folks on the online chat sent me this link:
Configure dynamic DNS on your modem | CenturyLink
##Actual behavior
I'm sitting around saying "duhhhhh" because I feel lost trying to navigate this interface. Netgear was way easier. Has anyone already set one of these up correctly?
Are you trying to setup Dynamic DNS?
Configuring Pi-hole in your router has nothing to do with DynDNS.
Have a read of Pi-hole's post install recommendations and try to adopt that for your specific router.
Thanks. No, I want a static DNS (the RPi 3 with Pi-Hole) and no other DNS. I want all wired and wireless traffic to go through it. The guy at Centurylink didn't understand me, I fear. Thanks for the link. I will review.
The information is generic, so you'd still have to figure how to apply that for your router.
It usually comes down to two configuration options in your router:
a) distribute Pi-hole to your clients as local DNS server via DHCP
commonly a LAN or DHCP setting
(clients acquiring a DHCP lease from your router will talk to Pi-hole for DNS)
b) have your router use your Pi-hole as its sole upstream DNS server
commonly a WAN or Internet setting
(clients will talk to your router for DNS, and your router will forward their requests to Pi-hole)
a) would be preferred, but some router's may just allow to configure b).
In both cases, you'd end up with a working Pi-hole, but the latter won't allow you to attribute queries to indivual clients.
If your router supports neither, you could still try and configure each of your devices manually to use Pi-hole for DNS.
Thanks. So far this is not working. The Actiontec C3000A router does appear to allow you to put in a primary and secondary DNS under WAN and DHCP. I have tried it both ways and totally killed my Internet each time. A funny observation was that the router's device table assigns a different IP address to my RPi than the PiHole admin console lists under IPV4 Addressing. Perhaps that's an issue. I will continue investigating and post my solution if I can find one. Otherwise, PiHole has to wait until I get new equipment. If I was able to upload it successfully, here is a screenshot of the DHCP screen under LAN, unchanged from Centurylink defaults.
If you didn't opt for a static IP during installation, you need to configure a fixed IP address / DHCP lease reservation for your Pi-hole machine in your router, and you have to use exactly that IP address in your router's DNS settings.
Pi-hole will show the IP configured at the time of its installation.
The following command will list IPv4 addresses as currently assigned when run from your Pi-hole machine:
ip -4 address
If that doesn't match an IP address from Pi-hole's UI, please run
pihole -r
and choose Reconfigure to make Pi-hole aware of its changed IP addresses.
Just a note to other users: I was afraid that running "reconfigure" under the -r command would wipe out my white and blacklists, but it did not. So this was the solution to the mismatched IPs.
