DHCP Relay with InfoBlox not function

I have problem with DHCP relay problem with infoblox, from mikrotik there it show request, but no respond…
anyone having this issue? it is need to bypass some port no?

Here is my setting:

/ip address
add address=10.20.10.11/24 interface=ether1 network=10.20.10.0
add address=10.22.0.2/16 interface=ether11 network=10.22.0.0
/ip dhcp-relay
add dhcp-server=10.20.10.10 disabled=no interface=ether11 name=InfoBlox
/ip dns
set allow-remote-requests=yes servers=8.8.8.8

10.20.10.10 is my Infoblox DHCP server…
My out bound traffic for local user is at ether11, and range starting 10.22.0.0/16 network.
My in bound(internet) traffic is from ether 1 and having address 10.20.10.11/24 i also use ether 1 to get connection to DHCP server ip address.
I am able to ping dhcp server.
