Firewalld - source IP not working

New to firewalld, and having an issue trying to emulate my old iptable ruleset.

Server has one network interface, which I usually only allow SSH in from certain IPs, I know I can do this with rich rules but have read that this is sub-optimal.

So, I created a new zone, ABCinternal, added a couple of source IPs that are allowed to SSH in, reloaded the firewall and IPs other than the ones listed can still SSH in - what am I missing here?


Code:
[root@rhel7-test zones]# firewall-cmd --zone=ABCinternal --list-all
ABCinternal (active)
  target: 
  icmp-block-inversion: no
  interfaces:
  sources: 192.168.1.10 192.168.1.99
  services: ssh
  ports: 
  protocols: 
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules:

NAME
firewalld.conf - firewalld configuration file SYNOPSIS
/etc/firewalld/firewalld.conf DESCRIPTION
firewalld.conf is loaded by firewalld during the initialization process. The file contains the basic configuration options for firewalld. OPTIONS
These are the options that can be set in the config file: DefaultZone This sets the default zone for connections or interfaces if the zone is not selected or specified by NetworkManager, initscripts or command line tool. The default zone is public. MinimalMark For some firewall settings several rules are needed in different tables to be able to handle packets in the correct way. To achieve that these packets are marked using the MARK target iptables(8) and ip6tables(8). With the MinimalMark option a block of marks can be reserved for private use; only marks over this value are used. The default MinimalMark value is 100. CleanupOnExit If firewalld stops, it cleans up all firewall rules. Setting this option to no or false leaves the current firewall rules untouched. The default value is yes or true. Lockdown If this option is enabled, firewall changes with the D-Bus interface will be limited to applications that are listed in the lockdown whitelist (see firewalld.lockdownwhitelist(5)). The default value is no or false. SEE ALSO
