Specify IP address range in LUCI firewall configuration

Is there a way to specify an arbitrary address range in the LUCI port forwarding dialogue, or does it only accept masked addresses? I need to specify a range that is not on a netmask boundary.

e.g. 192.168.1.0/24 works but 192.168.1.100-192.168.1.119 does not. The iptables syntax for arbitrary IP address ranges is somewhat opaque -m iprange –src-range 192.168.1.100-192.168.1.119.

The tip underneath the field suggests that a range can be used, but i suspect it only means a netmask range.

Thanks,

Not sure this is correct or not. You can put:
192.168.1.100/192.168.100.119

In correct CIDR notation:

192.168.1.100/30
192.168.1.104/29
192.168.1.112/29

I believe the boundaries are correct here.
