[kilocho]

Hello,
i have a problem with my Centos Server. I have installer VestaCP with postfix mailserver. But its impossible to connect via y public ip with the ports 443, 8083, and even 25. It works when i do telnet to localhost or with local ip but doesnt with the public ip.
Please help me i dont know what to do.
Thaink you

We don't support any systems with control panels on them so you'll need to ask VestaCP for support.

Its not a probleme with the panel i believe its a probleme with iptables please. because only port 80 is open.

CentOS 7 uses firewalld (unless you manually have switched to iptables).

I have switched to iptables. How do i open ports ?

This is a good intro to iptables:

You need to ask vestacp for support. We know nothing about control panels here and many of them, including it seems from their web page VesatCP, include management of iptables rules among their functions. Doing things in a way that appears to work may in fact then break once the CP gets involved.

Are you on an ISP which has those ports open? Might not be your firewall or your CP.
If you're server is behind a NAT on a home based internet service from a major ISP then there's a chance the ports are blocked further upstream and no amount of configuration will work around that. You'll have to move up to a business account where the ports are open.. Just my WAG.
