Dear all,

I'm running gre tunnels with Fortinet Firewall (Hub VNP). I'd like to know how to set up a DHCP relay.

The schema is quite simple : Site1 (Mikrotik) ==> Fortinet (UTM) ==> Site 2 MKT

The DHCP server should give addresses from Site1 to Site2

If someone could help me?

Thank you in advance,

Kind Regards,

Go to the Site 1 router
Click on IP->DHCP relay.
Enter the details.
Go to the DHCP server.
Allow the remote network that you have put the relay on, with a lease range.

Hello, the problem is that i can not choose the gre interface in the drop list (interface).

Regards,

You must choose your LAN interface there. The place where your DHCP clients are.

Ok thank you for your help, i'll try this

Hello pe1chl,

I'm not able to achieve ths scenario. I have read some tutorials and i could see i need to activate dhcp relay on Site2.

I have never do this, so please be patient

Thank you in advance,

If someone needs an update, i could get it working

I'd set WAN IP's in DHCP Relay parametres and use interface WAN in the DHCP server Interface.
