OPNsense WAN DHCP

I have ISP router in bridge mode. My buggy tp link openwrt does get DHCP lease without problem with spoofed MAC.

Today I upgraded to OPNsense. I cant get WAN DHCP lease. I tried everything. All the time I troubleshoot with tcpdump. Played with DHCP Option 60 & 61. Nothing. Its like somewhere packet being dropped, however I tested my Mikrotik CRS210 VLAN filtering.
