Trying to set up NPM with cloudflare on custom ip (br0)

Hi,

I'm looking for help to know if it's possible to do this.

First, NPM with cloudflared on the bridge network is working flawlessly. Let's say my unraid server is 192.168.1.10, using default port values for NPM and cloudflared docker makes my apps accessible trough my custom domain.

I'm trying to make it accessible to my pi-hole to create *.local.domain.tld to use with app that I don't want to expose. So, I'm trying to give a custom ip to my NPM docker, ie 192.168.1.11, using br0. I can access NPM dashboard but cloudflare throw me this error :

ERR error="Unable to reach the origin service. The service may be down or it may not be responding to traffic from cloudflared: dial tcp 192.168.1.11:18443 connect: connection refused" cfRay=*** originService=https://192.168.1.11:18443

I've tried to give access to give host access to custom network, as it may be a problem with macvlan.

Am I doing something wrong or is it just possible to do ?

Thanks
