Mastering Proxmox - Third Edition

[group <name>]

This segment clumps all the security groups created in the Datacenter zone. It shows the name of the security group and the rule added to the group. In the preceding screenshot, we can see that we created a security group named webserver and added macro rules in order to allow HTTPS, HTTP, SSH, and FTP traffic. We can also manually add rules in this segment by defining a protocol and port. For example, if we want to allow the TCP traffic to port 565 only from IP address 10.0.0.2, we will add the following line of code to the webserver security group:

IN ACCEPT -source 10.0.0.2 -p tcp -dport 565
