# Software Implementations
## Uncomplicated Firewall - UFW
[UFW](https://en.wikipedia.org/wiki/Uncomplicated_Firewall) is a linux software stack to very easily implement a firewall. It works by changing [iptables](https://en.wikipedia.org/wiki/Iptables). There is a known issue when using ufw together with [[Docker#Networks|docker networking]], since both modify iptables.
