A litle PHP script utility for renew IPTABLES firewall rules.

Requirements

apt install php-cli sqlite3 php-sqlite3

Installation

Copy the updateNoIp.php to /usr/local/bin/ or another directory do you want.

You can use in CRONTAB or Systemd-timer

In CRONTAB with root

contrab -e

and than add this line if you copied the script to /usr/local/bin/

CRONTAB:

/1  * /usr/local/bin/updateNoIp.php

SYSTEMD-TIMER: - copy update-noip.server and update-noip.timer to /lib/systemd/system - create a link into /etc/systemd/system/timers.target.wants/ - run systemctl daemon-reload command

You can see with systemctl list-timers command

The script will create the SQLite database and then you must insert your noip hostname and external ip into this database.

You also edit your iptables rules into script and in your iptables firewall.

In script there are those iptables rules. Change for your needs.

system('iptables -t nat -D PREROUTING -p tcp --dport 5432 -s ' . $row['ip'] . ' -j DNAT --to-dest 192.168.121.250');
system('iptables -t nat -A PREROUTING -p tcp --dport 5432 -s ' . $ip . ' -j DNAT --to-dest 192.168.121.250');
