Change in dhcpd.conf.local not showing on webui after dhcpd restart

I need to change my netmask for GREEN, as I have run out of ip addresses. When I change dhcpd.conf, either directly or by adding it in dhcpd.conf.local, dhcpd will restart without error, but the changes are not reflected in the webUI. If I then save the configuration showing on the webUI, it replaces the changes I made in dhcpd.conf.

How can I change my netmask?

As a sidenote, to make changes in dhcpd.conf.local, as suggested in the wiki, I had to delete the GREEN network information from dhcpd.conf and add it in with the changes in dhcpd.conf.local. The problem with this is that if I then save from the webUI, it leaves me with duplicate definition blocks for GREEN.

Changing your GREEN network is not a task of dhcpd ( the component configured by the dhcp WUI page ), but a system change. dhcpd hands out only IPs of the network.

Networks are defined from the CLI by setup. I recommend to use the console, because changes to the network config may cut your connection.

I did not realize I could run setup again once already set up. That worked, thanks!
