How to control outgoing connections with firewalld?

Question

linux

Good afternoon.
Available: CentOS 7 + firewalld
Setting up inbound connections with zones and rules is easy and hassle free.
However! How to set up strict control of outgoing connections?
For example, I want this particular machine to be able to connect on port 666 to a neighboring machine (let's say 192.168.1.2), but not be able to connect to anyone else on port 666. Is it possible?

Answer 1

Perhaps something like this: firewall-cmd --permanent --direct --add-rule ipv4 filter OUTPUT + add the ip to which you are connecting + port and add a second drop rule to drop other packets.
If you do the config remotely, don't block yourself :)
