Hi .. I need open port 80 on my ubuntu server only for two or three dynamic IP address.
I use Iptables for security and I open port 80 for static IP. Now I want open port for another IP but that IP changed every 24 hours. If I use that IP today and put in firewall tumorrow that IP is expired and I must put again and so over and over again.
Anyone who has a solution for this please contact me.
