How to make free5gc access the services on the MEC?

How to make free5gc access the services on MEC? It can access the Internet, , but I can’t access the MEC server near the base station in the LAN. My free5gc is deployed in k8s. The video server is deployed on the MEC. How can I configure it.

I use free5gc of the latest master branch, oai-gnb and terminal module.
