Fortigate DHCP

[LEO08]

Hello,

 The Fortigate NGFW we are using in our current location is a 60D. The 60D is being used as the main firewall, DHCP and DNS device. I have been tasked to separate 2 departments into different networks but keep the same DHCP scope for the new networks. My plan is to divide these departments into VLANs however I don’t know if/how you can setup the Fortigate to provide one DHCP scope to separate VLANs. Can I setup one VLAN to relay DCHP to the other VLAN?

Hi,

DHCP on 60D could use more memory and can causes disruptions in network as UTM could go into conserve mode due to less memory availability. I suggest please use single dhcp server for one network range only.

The error could be like this "FortiGate has reached system connection limit for 159 seconds"

Thanks
