 ## Known Issue
 
-* The first run of a playbook may be long (~8 minutes) just after the (re)start of `nftables` service.
+* The 10 minutes delay at the first run is finally fixed by allowing the host to reset SSH connection (flags `rst, psh | ack`) (see #1).
-  * Probably due to Ansible/OpenSSH Specific default Settings, the outgoing connections for Ansible/SSH will be blocked :

-  * This only happen at the first run on new clean host. The next runs will works without any delay.
