2. CSF module installation in Webmin

CSF module installation is done through Webmin interface so first you should log in to you Webmin instance. By default the address is:

http://your-server-ip:10000

After successfully login you should select "Webmin" and "Webmin Configuration":

In "Webmin Configuration" select "Webmin Modules":



In "Webmin modules" select "From local files" and specify the path to module archive and isntall module.

/usr/local/csf/csfwebmin.tgz

NOTE: if you are using "Authentic Theme 18.10" you should remove "csf.min.js" file because of a bug:

rm /usr/libexec/webmin/authentic-theme/extensions/csf.min.js -f

3. CSF configuration

After successfully installation you can now configure your ConfigServer Security & Firewall. Select "System" and "ConfigServer Security & Firewall" in your Webmin instance:



You should now see that there is two notices that we need to take care of. So select "ConfigServer Firewall" and then select "Firewall Configuration":



First we will turn of testing mode:



And then we should restrict syslog/rsyslog access:



After these changes press the button "Change" at the bottom of the page and "Restart csf+lfd" afterwards.

That it, now you have fully working ConfigServer firewall. For more information regarding CSF please visit their
