Bonjour,
Depuis que j'ai installé ufw sur cette Debian, je note un délai de plusieurs secondes lorsque je me connecte depuis Windows en SSH. Dois-je ajouter quelque chose dans la config ?
Merci.
```
~# ufw status
Status: active
To Action From
-- ------ ----
Anywhere ALLOW 192.168.0.0/24
Nginx Full ALLOW Anywhere
Anywhere (v6) ALLOW fe80::/64
Nginx Full (v6) ALLOW Anywhere (v6)
```
``` 
~# journalctl | less
