Hi,

Here is some more info:

# firewall-cmd --list-all
public (active)
   target: default
   icmp-block-inversion: no
   interfaces: ens33
   sources:
   services: cockpit dhcp dhcpv6-client dns http https imap imaps mdns 
ntp pop3 pop3s rpc-bind samba smtp smtp-submission smtps ssh tftp
   ports: 587/tcp 82/tcp 628/tcp
   protocols:
   forward: yes
   masquerade: no
   forward-ports:
   source-ports:
   icmp-blocks:
   rich rules:
         rule family="ipv4" source address="10.1.0.0/16" port port="993" 
protocol="tcp" accept
         rule family="ipv4" source address="10.1.0.0/16" port port="53" 
protocol="udp" accept

So I think it should be open.  Although I had to open it by port instead 
of by service name.  I guess I could create a config file for it.  
Although, I'm not sure that would matter much.  Doing a netstat and 
greping for 628 doesn't show anything:
