delete/change a rule, need option to kill open connections

[asdffdsazqqq]

hello and thanks,

need option that that when a rule is deleted, an open connection is killed.

current behavior

1. have rule - {"Action": "accept", "Users": ["en08"], "Ports": ["pi4:22"]}
2. have open connection from en08 to pi4:22
3. delete rule
   4.the connection stays open

proposed behavior

1. have rule - {"Action": "accept", "Users": ["en08"], "Ports": ["pi4:22"]}
2. have open connection from en08 to pi4:22
3. delete rule
   4.the connection is killed
