I spent all day today trying to get the routing to work correctly between Tailscale, Nginx and Adguard.

Basically I wanted to be able to be able to use **http://immich.network ** to route to 192.168.1.2:9000

I wanted to share the steps I took so people don't have to go through what I did.

First a few things Local Server IP: 192.168.1.2

1. I installed Ngnix and Adguard, in a Docker Containers, and gave Adguard IPs 3000, 3001 instead of 80 and 443 because Ngnix took it.
2. I went to my router and made it use the DNS: 192.168.1.2
3. I configured Proxy Host in Ngnix ..... immich.network => 192.168.1.2:9000
4. I configured DNS rewrite in Adguard .... *.network => 192.168.1.2

At this point I was able to use http://immich.network finally. I installed Tailscale to be able to access when I'm outside but http://immich.network didn't work.

These helped me https://tailscale.com/kb/1019/subnets + https://tailscale.com/kb/1054/dns?q=global+nameserver

5. I created a subnet..... tailscale up --advertise-routes=192.168.1.0/24
6. I approved it on Tailscale login

At this point I was able to access home server using its local IP 192.168.1.2 but I couldn't get http://immich.network to work.

7. I created a nameserver dns with split DNS but I used my local ip.. 192.168.1.2 => network

Finally everything is working.. I have a feeling that I'm doing it wrong but I'm too tired and it's finally working.
