# UFW
|
|
|
|
[UFW (Uncomplicated Firewall)](https://code.launchpad.net/ufw) is a program to
|
|
manage a netfilter firewall.
|
|
|
|
## Usage
|
|
|
|
### Block specific IPs
|
|
|
|
To block the whole traffic from a specific IP to your computer run:
|
|
`ufw deny from <ip> to any`
|
|
This will not send a reject response, so the target of the block won't know he
|
|
was blocked.
|
|
If you don't care if the target knows you can also run:
|
|
`sudo ufw reject from <ip> to any`
|
|
|
|
### List all rules
|
|
|
|
To show all rules you can run:
|
|
`ufw status`
|
|
or:
|
|
`ufw status numbered`
|
|
if you want to have a list of all rules with according numbers.
|
|
|
|
### Remove rules
|
|
|
|
Locate the rule you want to remove by showing all rules (numbered).
|
|
Then run:
|
|
`ufw delete <number of rule>`
