RouterOS General

For some reason I need to add DHCP option 58/59/249
But It didn’t take effect
Anybody knows why?
what’s the version that works fine for these DHCP options?
Many thanks!

Your best bet is always the latest version: 5.6.

I tried 5.6 , however , a serious bug occurs : when I have two interface(in ROS) bridged with the host(Ubuntu10.04),
I send ARP request to any IP of the two interfaces , I got TOW ARP replies.
Strange? But it is.

and version 5.6 doesn’t support DHCP options 15/58/59 ,too
