Rancher server with cloudflare tunnel

I have followed this doc - Helm CLI Quick Start | Rancher Manager
and after running the below command

helm install rancher rancher-latest/rancher
–namespace cattle-system
–set hostname=<IP_OF_LINUX_NODE>.sslip.io
–set replicas=1
–set bootstrapPassword=<PASSWORD_FOR_RANCHER_ADMIN>

While, I am able to access the rancher node from my internal network with hostname resolution set in /etc/hosts but through clodflare tunnel i cannot set the access. I cannot see the mapping of ports on my host. So not sure how to enable access of my rancher node through cloud flare tunnel?
