Minifirewall
|
|
=========
|
|
|
|
Minifirewall is shellscripts for easy firewalling on a standalone server
|
|
we used netfilter/iptables http://netfilter.org/ designed for recent Linux kernel
|
|
See https://gitea.evolix.org/evolix/minifirewall
|
|
|
|
## Install
|
|
|
|
~~~
|
|
install -m 0700 minifirewall /etc/init.d/minifirewall
|
|
install -m 0600 minifirewall.conf /etc/default/minifirewall
|
|
~~~
|
|
|
|
## Config
|
|
|
|
Edit /etc/default/minifirewall file:
|
|
|
|
* If your interface is not _eth0_, change *INT* variable
|
|
* If you don't IPv6 : *IPv6=off*
|
|
* Modify *INTLAN* variable, probably with your *IP/32* or your local network if you trust it
|
|
* Set your trusted and privilegied IP addresses in *TRUSTEDIPS* and *PRIVILEGIEDIPS* variables
|
|
* Authorize your +public+ services with *SERVICESTCP1* and *SERVICESUDP1* variables
|
|
* Authorize your +semi-public+ services (only for *TRUSTEDIPS* and *PRIVILEGIEDIPS* ) with *SERVICESTCP2* and *SERVICESUDP2* variables
|
|
* Authorize your +private+ services (only for *TRUSTEDIPS* ) with *SERVICESTCP3* and *SERVICESUDP3* variables
|
|
* Configure your authorizations for external services : DNS, HTTP, HTTPS, SMTP, SSH, NTP
|
|
* Add your specific rules
|
|
|
|
### Docker
|
|
|
|
To use minifirewall with docker you need to change the variable *DOCKER* from _off_ to _on_
|
|
Then, authorisation for public/semi-public/private ports will also work for dockerized services
|
|
|
|
|
|
**WARNING** : When the port mapping on the host is different than in the container (ie: listen on :8090 on the host, but the service in the container listen on :8080)
|
|
you need to use the port used by the container (ie: 8080) in the public/semi-public/private port list
|
|
|
|
## Usage
|
|
|
|
~~~
|
|
/etc/init.d/minifirewall start/stop/restart
|
|
~~~
|
|
|
|
If you want to add minifirewall in boot sequence:
|
|
|
