| Summary | 0002687: drop rules do not block connections which are already ESTABLISHED | ||||||||||
| Description | We have setup a rule to allow SMB-All from a server in ORANGE to a server in GREEN. All works fine. We copied some files and after that we disabled the rule. After disabling the rule all SMB traffic is still allowed. See also connections in status screen with port 445. We have to logout and login at the server in ORANGE to have no access to the server at GREEN. So it looks like disabling the rule does not affect to sessions that exists. All SMB session should be killed if we disable a SMB rule. | ||||||||||

firewall rules affect only the connection initiation. due to the statefulness established connections will not be blocked. Can't change this easily, otherwise we degrade firewall performance and remove statefulness Killing every established connection affected by a rule is not that easy also, since we can't identify them only with the rule-information, because they are not that specific most of the time. We can implement an option to kill an established connection manually, through connections.cgi |

Yes. Please implement something like that. Is there a workaround possible? Maybe a command at the shell to kill established connections? |
