Okay, I’ve been trying to figure this one out for a while now and I just wanted to see if I could get any hints.
I am trying to send/recieve a DHCP request/response to a DHCP server across my network.
The DHCP server is connected to the ether1 interface of the RouterOS PC

If I am lacking any crucial info, lmk.
Because the DHCPDISCOVER message is a broadcast message, and broadcasts only cross other segments when they are explicitly routed, you might have to configure a DHCP Relay Agent on the router interface so that all DHCPDISCOVER messages can be forwarded to your DHCP server. Alternatively, you can configure the router to forward DHCP messages and BOOTP message. In a routed network, you would need DHCP Relay Agents if you plan to implement only one DHCP server.
This is covered in the manual, http://www.mikrotik.com/testdocs/ros/3.0/pnp/dhcp_content.php#.9.5
