Cloudflared: CF Tunnel can't access local network

Dear all,

I am trying to connect a device using the warp client to a private network. Thereby I followed exactly the instructions described in: Creating and connecting the tunnel worked and I was able to expose a local service to a subdomain without any issue. Unfortunately after connecting the warp client I can’t access my local network. The local IPs (192.168.1.x …) are not resolved. Is the above mentioned guide still up-to-date? As said everything is setup exactly as described there.

Hope someone could help out or point me to the right direction.
Thanks in advance
