The tunnel ports provided by each edge node are different(10350++). You can schedule the cloudcore(inner iptables manager) to the control-plane node or deploy the iptables-manager to the control-plane node.

Thanks for your reply!
Yes,I schedule the cloudcore to the control-plane node and set iptables manually,but I have a problem that when the address in my tunnelport configmap is the same as the address I used when deploying cloudcore is, ''kubectl exec'' can run normally, but it can't run at the different time, for example, when the content of the tunnelport configmap is:
# kubectl get cm tunnelport -nkubeedge -oyamland the address I used when deploying cloudcore is: 100.64.93.127 ,''kubectl exec'' will report an error:
apiVersion: v1
kind: ConfigMap
metadata:
annotations:
tunnelportrecord.kubeedge.io: '{"ipTunnelPort":{"192.168.142.6":10351},"port":{"10351":true}}'
# kubectl exec -it edge-pod -n kubeedge -- /bin/bash Error from server:
and the edge node will be not ready

Sorry, this is an incorrect description. Each CloudCore restart causes tunnelPort +1(10350, 10351, 10352 ...), which seems to be a historical issue.
From your description, it seems the port 10351 should be DNAT to the stream service, you can look at the iptables rules.
