Hi everyone, I have server with ISPconfig3. I know that ISPconfig block ssh attack by fail2ban. But I want to have secured ssh only to one IP address or more what I choose. So question is... If I make rules in IPTABLES will it make something with ISPconfig configuration? And another question is how to do that right? What will be right code for IPTABLES. Thanks a lot for advice!
You can limit ssh-connections to one or more ip. But i would just change the sshd-port in /etc/ssh/sshd_config. Maybe 222 To limit the acces with iptables: Code: iptables -I INPUT -p tcp -m tcp --dport 22 -s YOUR_IP -j ACCEPT iptables -I INPUT -p tcp -m tcp --dport 22 -j DROP
