First time user of pi-hole, can't make it work

Help
1

Expected Behaviour:

Hi! I'm (trying) to setup a pi-hole on ubuntu 20.10 and and huawei model b252s-23a. Im using the pi-hole as my DHCP server and pi-hole version us v5.2.3, AdminLTE v5.3, FTL v5.4. The localhost's ip is 127.0.0.1. I'd think that with this in mind my devices should connect to the pi-hole succesfully and i'd get use the internet and enjoy an ad-free expierence.

Actual Behaviour:

nslookup pihole 196.168.8.201
DNS request timed out.
timeout was 2 seconds.
Server: UnKnown
Address: 196.168.8.201

DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
*** Request to UnKnown timed-out

My devices don't connect to it and the pi-hole's dashboard doesn't show more than 1 (localhost). I've done my best to include everything I think you need to help me.

[Album] All relevant pics I could think of regarding my pi-hole

This is my first ever time posting here or even using pi-hole, so i'm sorry if some vital info is missing. There probably are some duplicates of this, but i've tried my best to go through them and so far nothing has helped

Edit: fixed typo of my pi-hole's ip and through some console commands i've found the ability to change my DNS server. So i have enabled my router(&disabled pihole) as my DHCP server and put the ip of my pihole as the primary & secondary dns servers, but this just leads to not being to open any websites (it can't find them). I've also done my best to go through my router's security settings to find possible problems. Also im usint ubuntu as a Vm. Here are some new screenshots some new pics regarding pihole - Album on Imgur.

Sounds as if some firewall is blocking 53 TCP + UDP:

Below is permissive allowing all:

pi@ph5:~ $ sudo iptables -nL
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Also check your router for security related settings that might block DNS queries on your LAN.

EDIT: ow ps, you should query for pi.hole instead of pihole eg:

nslookup pi.hole 196.198.8.201

EDIT2: And another note, that 196.198.8.201 IP address is a public IP!
You wont get support here if you run an "open resolver" that can be abused to direct an attack on other victims:

You have network issues: Your router is still active as DHCP server and advertises itself as DNS server. Additionally, two different IP ranges exist in your network (10.0.2.0/24 and 192.168.8.0/24) - I guess this is not on purpose?

Hi! After some researching I found a way to show my dns setting through some console lines. So i've tried something new and disabled my pihole's DCHP server and instead enabled my router as my DCHP server. This just leads to me not being able to open any websites because i guess the devices can't connect to the pi-hole?

Here are some new screenshots:

PS. I'm also new to networking in general and so I have no idea for example why i would have to different ip ranges? Maybe something to do with hamachi or zerotier?

Where is that Pi-hole instance running ?
On a Pi, some other hardware or maybe a VM in the cloud ?

So sorry about this mistake, i've accidentally put the given ip as 196.198.8.201 instead of the actual ip: 196.168.8.201 and btw thanks for the notice of the vulnerability of my sys. I've tested the correct ip and it seems to be safe.

Do you mean 192.168.8.201 ?

Below the range of private IPv4 addresses:

Its running on a old laptop with ubuntu as a vm

10

What does this mean and how would i get rid of the other one?

11

I would start by deciding which device should be the DHCP server - Pi-hole or your router and disable it on the other, respectively.
