DHCP leases question (deleting a dhcp lease manually)

jnana

Ok - it was great to find this so what I just want to confirm is that this part of the 1.2RC3 DHCP server gui at the bottom - with "enable network booting"

That is setting option 66 and 67 of DHCP. This company are about to turn up and I have to have this
option bootfile-name "Thomson/ST2030S";
next-server 10.10.0.1;

Set to make the phones find the server and config.

So just looking for reassurance.

Also still wondering if asterisk is going to be able to connect outward through the firewall. In the past I didn't have much luck making Asterisk work through a firewall but there are traffic shaping options related to asterisk.

These last weeks I have really been converted from ipcop and smoothwall - pfsense is really complete.

Thanks

I know this topic is rather old and kind of unnecessary but just to clarify if someone is really interested in removing expired leases

In the GUI, go to Diagnostics/Edit File and load /var/dhcpd/var/db/dhcpd.leases~

Delete the leases you want removed, then hit Save.

Do the same for /var/dhcpd/var/db/dhcpd.leases

Hmmm Deleting all the leases shown in the two files did not work for me, a reboot does however, although clearly this is a less preferable fix!

As onhel wrote: Try to press save on the DHCP config page after deleting the files.

You somehow have to trigger that the config gets reloaded.
A reboot reloads the config. Pressing save does too.

I had same problem ….. pfSense DHCP remembers all leased IPs and won't releases them even though 1 machine have several leases .
I changed the IP range, save it then put the old IP range back, save it again. That resolves my problem till next time the DHCP runs out of IP again.

Hello, just wondering if it actually worked

thanks

Verified.
Deleting the lease content information in those two lease files and then pressing the Save button in the DHCP Server page does update the current DHCP lease listing in the GUI.

Do i understand this correctly, if many PC have several leases and every ip is used there will be no more leases until i do whats described here.
