فايروول CSF Firewall سماح Allow Domains Having Dynamic IP
​How to whitelist a hostname in ConfigServer Security and Firewall installed (CSF)




If your server has ConfigServer Security and Firewall installed (CSF), then you may find it necessaryto whitelist a hostname as opposed to an IP address.
CSF has a file specifically for allowing hostnames called "csf.dyndns". Fully Qualified Domain Names (FQDN) are checked at a configurable interval of seconds, to poll for a change in the IP address. If the IP address has changed iptables will be updated!

الطريقة من خلال WHM :

افتح لوحة firewall ثم انزل الى lfd - Login Failure Daemon
وادخل على lfd Dynamic DNS وهى خاصية تقوم بعمل Allow دائما




داخل lfd Dynamic DNS ادخل بعد # رابط الموقع / الهوست فى كل سطر
هنا تم وضع رابط من امازون aws ليس له اي بي ثابت.



ثم داخل عدادات الفايروول settings
وضع قيمة 300 امام DYDNS وهى هتعمل تحديث للاي بي كل 5 دقائق




---------------------------------------
طريقة اخري من خلال Terminal
---------------------------------------

To whitelist a hostname:
1) SSH to the server

2) Open the file "/etc/csf/csf.dyndns" and add the hostname.

3) Open the file "/etc/csf/csf.conf" and set DYNDNS = "300" (which would check for IP updates every 5 minutes).
Note: If you want the activity of the IP also ignored, setDYNDNS_IGNORE = "on"

4) Restart the firewall
That's it. The hostnames in csf.dyndns will automatically be allowed and the rules will refresh every 5 minutes.
