I assume that using the trashcan icon next to that entry did not work? If so, edit file /etc/dnsmasq.d/05-pihole-custom-cname.conf and delete it there.

We will need more information on what you are trying to do. Start with posting the current contents of the file listed above.

cname=google.com,youtube.com/watch?v=dQw4w9WgXcQ

Gives google.com’s server IP address could not be found.

4

This is not a valid domain name.

5

I know, but how can I make it redirect to a domain with a url path?

Or must I just setup a simple webserver which redirects and it's not possible with DNS?

6

You cannot with a DNS server that works at the domain level. You need a proxy server.

7

oh k thanks

8

okay say I have setup a proxy server on rickroll.local, which redirects to youtube (and it works, I tested it)
cname config

so like this would redirect pornhub.com to rickroll.local to youtube right?

9

Try it. There's a limitation in the Target Domain that's not documented. The Target Domain needs to be a domain that Pi-hole is already managing. The test to see if it will work is to dig the CNAME and see if there is an actual IP address returned, or just a CNAME record without the additional IP address. The latter will not work.

11

I get

pornhub.com refused to connect.

12

Do a dig pornhub.com @<pi-hole IP> and post the response.

That's all the information that Pi-hole can provide. I think the issue then is on the proxy.

Try using curl -IL http://pornhub.com and see what headers are reported and if the problem is at the proxy.

Note, https://pornhub.com likely will not work as TLS prevents most attempts to impersonate sites.

https://pornhub.com gives connection refused

http://pornhub.com gives

Your nginx proxy is not configured correctly.

17

How would I configure correctly?

server {
        listen 80;
        listen [::]:80;

        server_name rickroll.local;
        rewrite ^/$ http://youtube.com/watch?v=dQw4w9WgXcQ permanent;
}
18

That's not something we can advise on. It looks like it's redirecting to http://pornhub.com/admin/ and not rickroll.local.

19

I guess that's pi-hole redirecting it to /admin is it?

20

Pi-hole uses lighttpd.

21

I set it up to use nginx
