Project to Project communication in rancher

Hi Team,

I am creating a project in rancher with name ABC and it has two namespaces in it say appserver and webserver . The namespace appserver contain my front end application pod and webserver namespace contain my backend application pod. Now , I have another project with name DEF and it has one namespace odb inside odb , there is one oracle pod . Now , the query is: Can the pod inside the namespace webserver of project ABC connect to the oracle pod inside namespace odb of project DEF?

In short, from one name space of one project to another project namespace communiation can possible or not . Please advise.
