Ufw comes with preloaded defaults for some commonly used programs, and they are automatically activated when you make a rule by specifying the name of the program. Other rules may be added in the same way by simply specifying a name of the program (Deluge, Transmission). Therefore, you must create a rule which allows SSH connections, by typing: For example, by default ufw denies all of the incoming connections, which will make it a problem if you are using SSH. Note: With this command you will also be able to see all of the defaults and rules which you have applied.Īllowing rules is quite simple from the command line, and it is sometimes necessary. Next, it is recommended to verify that the firewall is enabled by typing: For normal users the following defaults will do just fine. Note: it may be disabled the same way, by replacing enable with disable.

However, simply installing the firewall will not turn it on automatically, nor it will have any rule set by default. Uncomplicated Firewall can be easily installed by typing this command into the terminal as a super user:
