Are any of you using firewalld to manage outbound traffic on a server?
I want to do something on a system that differs from the default allow 
all out/only block inbound config,

For example:
1.  Allow (for example).  192.168.1.0/255.255.255.0 inbound on tcp 22
2.  Restrict all outbound traffic, except:
	a.  The usual "stuff" such as NTP, DNS, LDAP
	b.  tcp 22 outbound restricted to 192.168.1.50
         c.  tcp 80 and 443 outbound restricted to 192.168.1.80
I know how to do #1 easily with rich rules.  Are any of you doing 
something similar to the #2 with firewalld?
