Hi Community,
Is it possible to have the Fortigate 100F act as DHCP Server and "Relay" in the same VLAN?
I want Clients to get there IP from the Fortigate but everything else forwarded like an additional IP-Helper.
This is mostly for OS Deployment. I know you can configure DHCP Options but this will limited the capability of deployments to specific architectures and devices.

So how would the fortigate know who and what to relay?

It doesn't have to. It answers and forwards "everything" to the additional helper.
First come first serve for the client. Fortigate shouldn't bother what the clients receives or how it is handling it.
Re-design your network so that you have a separate VLAN for OS deployments only.

This makes no sense to me. Any requests on the VLAN would get IP addresses in the VLAN. What's to forward?
E.g.: Boot Options. IP-Helpers serve more than just DHCP.

Will not change the request/question. OSD already is a separate VLAN..
Other IP helpers are handled by the IP helpers. Boot options would come along with the IP assignment, no? PPTP, TFTP, FTP, etc are handled in the System>Session-helper section.

1. Client boots using PXE.
2. Client broadcasts for DHCP Server and PXE server.
3. Fortinet (DHCP Server) offers DHCP service.
4. SCCM (PXE Server) offers PXE service.
5. Client asks Fortinet (DHCP) for IP. -> Client gets IP assignment.
6. Client asks SCCM (PXE) for boot instructions (e.g. NBP File).
7. Client downloads NBP and runs it.
DHCP Server could be any system. I could remove Fortinet as DHCP Server and use two or more ip helpers instead but I'd like to limit the count of systems.
OK. Thank you for the clarification. Sorry I can't be of more useful assistance. Good luck.

I know its not what you're asking, but what's the reason for not having the remote DHCP server supply the IPs so you can run a conventional relay config?
