Desktop 4.29.0, network host

How can I obtain the specific client IP address when other clients connecting to my Ubuntu container, which is running on a Windows host with IP 172.21.53.209, but all connections show as coming from 127.0.0.1. When I do not set host network , all incoming connections show the IP as 172.17.0.1.
I want to obtain the actual client IP address in my container(ubuntu)
