Add Multiple DHCP reservation on Fortigate 60D

[Donaire]

Hey guys, 

How you doing?

Well, I will migrate from DHCP on Windows Server to DHCP on fortigate. I have lot of resevations on the server, is there a way i can make this reservations on Fortigate without doing it one by one. 

Like a scrip or something? 

For example on Windows server i can do it through PowerShell, with something like this: 

Add-DhcpServerv4Reservation -ScopeId 192.168.0.0 -IPAddress 192.168.0.XX -ClientId "XXXXXXXXXXXX" -Description "Reservation for XXX"

And I just replicate for every reservation I want. 

Appreciate your help, 

Thank you

I'm not sure why you would want to do this as Windows DHCP is far better IMO, but here is a thread from a few months back addressing exactly this: https://forum.fortinet.com/tm.aspx?m=190549  Hope that helps.

hm I modified my prgram from the other thread to read windows dhcp reservervations csvs as exported via Powershell and create FGT cli script from it.

Seems to work so far.

I just will have to publish this one...

yeah I remember that thread. Just the programs mentioned in there might wer written for unix dnsmasq reserfations afair. I am not sure wether windows dhcop can export its reservations (and in which format)

, so you might have to code your own or change the existing if possible.

Update:

I've had a look. Seems not to be possible to export reservations in a usable way in gui. 

However there is powershell cmdlets that can do it:

Get-DHcpServer4REservation -ComputerName "yourdhcpserver" -ScopId yourscopesubnet | Export-Csv -NoTypeInformation  -Path <pathandnameofcsvfile>

this will create a .csv that contains all needed information.

Well, Windows dhcp can export to csv file.  It is as you said the programs mentinoed in the past thread are quite different but anyways they gave me some insight. Perhaps I have to try to code it myself.

I apologize for the delay but I didnt find the time earlier :(

Here is the modified one: https://www.dropbox.com/s/p7gkuiqya6yix15/windhcp2fgt.zip?dl=0

As the other one it does almost not contain any error handling and you may use it at your own risk.

It is released under cc-by-nc license (and as said inner-company-use to me is not commercial).

Also I just looked at the result and it looked correct but I never actually fed a Fortigate with it.

Hope it is still of some use to you though...

Thank you very much, I will try it and let you know of the outcome.  Definitely, it is still helpful...
