I’ve set some DHCP options via Webwig: IP->DHCP Server->Options: (15,252,114,2)

In IP->DHCP Servers->Network I’ve set this options:

But in Wireshark I’ve saw only some options: (15,2):




What’s wrong?

DHCP options are sent only if client is requesting them.

What’s a point to do that?
When I used FortiGate 60C instead Mikrotik - I saw all options (15,252,114,2)

A DHCP server does not advertise itself. It only responds to requests. If no device requests a DHCP assignment, the DHCP server just sits there waiting.
You might want to take a look at this link to better understand how DHCP works:

Or for Mikrotik’s implementation and configuration of a DHCP server:

Ok, I’ll read.
But can you explain: same network, same client. Router FortiGate 60C send all my DHCP options (I saw it in wireshark). But Mikrotik - only several options?
