This is my post to the proxmox forum but I got no help. Maybe someone here can help. Hi, I'm new to proxmox. I'm a newbie. I like proxmox so far I'm just having some problems setting up my first server. Pleas excuse my newbie english. I have my first server up and running(debian 8) with internet. I just have one MAJOR problem. I have Ispconfig 3 (http://www.ispconfig.org/ ) installed ( https://www.howtoforge.com/tutorial/perfect-server-debian-8-jessie-apache-bind-dovecot-ispconfig-3/ ) . How do I open all the ports needed to access the vm/container from the outside world (ex. ssh,ftp,panel)? Ports like 21,22,80,443,5080,8080.
