      Hello, I started using pfsense for a few weeks now and I'm having my first blocking point when configuring advanced DHCP Client Configuration.
      In order for my box to work with my FAI I need to configure the following DHCP options: 61 Client Identifier, 77 User Class information, 60 Vendor Class identifier.
      Option 77 and 60 looks fine but option 61 looking at the packet it doesn"t appear. I need to specify the mac address value in this field

      This is my config in the send option field:
      dhcp-class-identifier "sagem", user-class "+FSVDSL_livebox.Internet.softathome.Livebox3", dhcp-client-identifier {mac_addr_hexU:}:90:XX:XX:XX:XX:b0
      ![](http://pfsense dhcp option.PNG)

      See attached screenshot for packet capture

        Ok I found the solution the parameters need to be in the correct order  60, 61, 77

        dhcp-class-identifier "sagem", dhcp-client-identifier 1:90:xx:xx:xx:xx:b0, user-class "'FSVDSL_livebox.MLTV.softathome.Livebox4"
