Hi,  
I have Proxmox. I have added IPs for VMS, and I have a couple of VMs running, but I am a complete noob at firewalls.  
My question:  
What is the recommended OVH firewall configuration for Proxmox?  
How do we deal with port ranges when configuring a firewall?  
The background:  
I want to configure the OVH firewall for my Proxmox server.  
I think I need to make rules to allow the following ports:  
TCP ports: 22, 80, 85, 111, 3128, 5900:5999, 8006  
UDP ports: 5404:5405  
I do not know how to create a single rule that deals with a range of ports.  
I found this post from 2017: [https://community.centminmod.com/threads/ovh-firewall.11469/#post-48899](https://community.centminmod.com/threads/ovh-firewall.11469/#post-48899) The author suggests rules but states, "I'm not even sure about the above rules. :("  
Thanks in advance for your help.
