Helm chart to install mongoDB as service with external access

I have a helm chart from bitrnami/mongodb to install mongodb on our k8 cluster. I also install mongoexpres with the same step. Mongoexpress can access the mongodb with an easy inside the cluster. But I also need to connect the mongoDB from outside the cluster but the same network. As sample: [login to view URL] is the ingress host to connect mongoexpress I want to connect the database from outside the cluster with: [login to view URL], currently no internet access just internal network. The cluster is not part of the internet, just an internal network. working with loadabalcner will cause in an error that no ip is available from metalldb. ClusterIP is not woring well NodePort also not. The job is to present a helm chart and maybe additional commands in k8 to connect the database external from cluster. Attached you can find a simple helm chart that shows how I install currently without external access.
