Setup Nat loopback under firewall-cmd

[Игорь Шевченко]

Hello, can you help me setup nat loopback with firewall-cmd?
Network work fine, but local pc could not connect to web server over
external interface.

Firewall settings:

#firewall-cmd --zone=external --list-all
external (active)
  interfaces: eth0
  sources:
  services: ssh
  ports:
  masquerade: yes
  forward-ports: port=80:proto=tcp:toport=80:toaddr=192.168.1.6
  icmp-blocks:
  rich rules:

#firewall-cmd --zone=internal --list-all
internal (default, active)
  interfaces: eth1
  sources:
  services: dhcp dhcpv6-client ipp-client mdns samba-client ssh
  ports:
  masquerade: no
  forward-ports:
  icmp-blocks:
  rich rules:
