Networking question - Why can't I telnet to the load balancer port of the public ip from within the same server

Rancher 1.x
1

I currently have an LB configured in rancher and has a pubic ip and port of 192.168.8.101:81 and I can hit this without issue with my browser from outside the VM where rancher and the LB is running.

BUT when I try directly from the local VM using a simple telnet to the ip and port locally on the same VM where the LB is running, I get connection refused. I can only telnet using the ip/port as assigned by rancher staring with 10.42. why is that?

Version info:

      Rancher
      v0.50.2
      
      Cattle
      v0.127.0
     
      User Interface
      v0.75.0
  
      Rancher Compose
      v0.6.2
