We will allow only your IP address to connect on port 22, 80 and 443.
Edit the iptables file located here:
vi /etc/sysconfig/iptables |
Change these lines:
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT |
To these new lines:
-A RH-Firewall-1-INPUT -m state --state NEW -s YOUR_IP_ADDRESS_GOES_HERE -m tcp -p tcp --dport 22 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -s YOUR_IP_ADDRESS_GOES_HERE -m tcp -p tcp --dport 80 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -s YOUR_IP_ADDRESS_GOES_HERE -m tcp -p tcp --dport 443 -j ACCEPT |
Restart the iptables service:
service iptables restart |
Check the status of the iptable service:
service iptables status |
