i cannot reproduce the issue. it works as expected. probably it is not related with webvirtcloud but libvirt config. can you check it with command line? (create network with xml)

create an xml file name like test.xml and contains specified directives.

<network>
  <name>testttt</name>
  <forward mode="nat"/>
  <ip address="192.168.123.1" netmask="255.255.255.0">
    <dhcp>
      <range start="192.168.123.2" end="192.168.123.254"/>
    </dhcp>
  </ip>
  <ip family="ipv6" address="2001:db8:ca2:2::1" prefix="64"/>
</network>

run command:
virsh net-create --file text.xml

feedback please
