Are you trying to do office mode assignment to the same network where the cluster VIP and interfaces reside?  Or did you mean "VIP" as the virtual IP of the DHCP request?.  I ask because your earlier screenshot showed 172.16.10.201 as the DHCP virtual address, but here you have 172.16.10.254.  Not sure which is which.  If you are trying to do office mode DHCP for the same local LAN, there's no way this is going to work.  I would expect the office mode DHCP pool needs to be a different network (maybe try 172.31.0.0/24, virtual address 172.31.0.1, scope range 172.31.0.100-254).

As for packet flow, if the server is on the same local LAN as the gateway, and you are certain you see packets going to the server, but the server isn't replying, then check the Windows server firewall config to make sure it's allowing DHCP requests inbound.
