DHCP over GRE Tunnel

RouterOS General
1

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).

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

If someone needs an update, i could get it working :slight_smile:

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