    I'm getting one device constantly issuing DHCPACK & DHCPINFORM (see below), I've seen some comments which have suggested issuing a 252 with a \n might work.

    In Services: DHCP server, theres an option in Additional BOOTP/DHCP Options to add additional parameters.
    If I wanted to add 252 would I use a Text or a String?

    TIA

      Is that the actual MAC that you're using? What is 192.168.10.3?

      https://doc.pfsense.org/index.php/DHCP_Server#Numbered_Options_Notes

      You want to send a null config url via option 252? Do you have a link to this suggestion?

      Edit: Ah, OK. Like this: http://wiki.openwrt.org/doc/howto/dhcp.dnsmasq#log_continuously_filled_with_dhcpinformdhcpack

      Edit: It expects a string:
      @http://tools.ietf.org/html/draft-ietf-wrec-wpad-01:

      The DHCP option code for WPAD is 252 by agreement of the DHC working
        group chair.  This option is of type STRING.  This string contains a
        URL which points to an appropriate config file.  The STRING is of
        arbitrary size.

        Not the actual mac, but its a TalkTalk tv box, not even windows, but I thought I'd give the windows suggestion ago before calling TalkTalk support to see what they suggest.

        I had looked on the actual draft web page earlier but couldnt see anything but wanted to double check anyway as a null for me is a 0 as in long pointers normally.
