Why tun0 send lots of packages to pods located in another node
Issue
- I tried to capture network packages from one of my node, use the adapter tun0 and found there are lots of packages were intermittently sent to pods located in another node.
- After checking the package via network tool, I noticed those are TCP traffic but did not contains complete handshakes, Only 1
SYNand 1ACK. - I want to know why tun0 send those abnormal TCP packages to such pods.
Environment
