pfSense

This looks not too hard to do, and will help those who would like to be able to see and manipulate disabled-DHCP-server settings, static mappings... while they are running DHCP Relay at the same time.

As a side-issue while looking at how server and relay interact I got annoyed with some of the way that the DHCP Relay UI functioned, and that is fixed up by https://github.com/pfsense/pfsense/commit/ac999f3b7894bd8d5fc35419a22cc2df39416e42

I am looking at the code - someone can assign me if they like.

Thanks, Phil. And yes, also when migrating the other way round (i.e., when moving your DHCP to pfSense), you want to have everything set up in advance, to minimize downtime.

One more thing I noticed - Status/DHCP Leases, on the contrary, is something that should not be accessible when DHCP server is disabled, since the data there make no sense in that case.

https://github.com/pfsense/pfsense/pull/3271 addresses the DHCP (v4) Server part.

Some fixups/enhancements to Status DHCP Leases in https://github.com/pfsense/pfsense/pull/3273
If DHCP Server is disabled, then Status DHCP Leases still shows the static mappings. That provides a place to see a table of all the static mappings, so maybe it is still useful? Or maybe it should say something about the DHCP Server being disabled so that the user is aware of that when viewing the status display?

Well yes, possibly the static ones (however, you can still see the same data in the DHCP Server GUI.) The rest (non-static) is just completely misleading noise and potentially years old irrelevant data. Perhaps just filter out everything but static leases from there when DHCP server is disabled?

While messing with this - perhaps a button to nuke the entire /var/dhcpd/var/db/{dhcpd,dhcpd6}.leases file would be useful to have somewhere in the GUI, cannot see any good way to mass nuke the leases via the GUI.

Works, thanks! 8-)
