DHCP with Bridge and Capsman issue

RouterOS General
1

I recently set up a bridge using the guide here (http://wiki.mikrotik.com/wiki/PTP_Links_-_A_Step_By_Step_Guide) and am having an issue with DHCP.

I’m using a RB750 as my capsman, 2 grooves (52HPn) as my bridge, and 2 basebox 2’s (RB912UAG-2HPnD) as my CAPs. When I connect everything without the bridge it works fine. Once I put the CAPs on the other side of the bridge, they will pull IPs from the DHCP server, but clients cannot get an IP address from the DHCP server. I keep getting “failed to obtain an IP address”.

I was originally running 6.38.1, but after seeing this http://forum.mikrotik.com/t/ros-6-38-serious-dhcp-server-problem/105259/1 I netinstalled everyting back to OS 6.36.4. Still have the same issue. Anyone have any ideas?

…and totally not a Mikrotik issue. Packetstorm from ISP equipment maxing the CPU on my RB750. I recommend using the dashboard for both uptime and cpu in winbox. Would have taken me longer to troubleshoot without it.
