| Description |
This article describes how FortiGate can act as a DHCP Server for both IPv4 and IPv6 at the same time. |
| Scope | FortiGate v6.X and v7.X. |
| Solution |
It is possible to have a dual stack and a FortiGate as a DHCP server for both IPv4 and IPv6.
It is possible to do that via GUI for the v7.0 firmware and above.
