Hey there,
After reviewing your project description its clear that you want someone to install freepbx system on your linux vps and also need to configure iptables and fail2ban.
I'm very experienced with System Administration, Linux Administration, Network Administration.
I'll be happy to do this project for you.
Thanks in advance for giving the opportunity to working with you.
Have a good day.
Best Regards,
Serazum Munir.
