It looks like the dhcp relay is misrouting requests from the new civi2001 server. The symptom is that the dhcp server sees the dhcpdiscover request coming from 10.195.0.1 rather than 10.195.0.33. Here's a dhcpdiscover request from a host that works correctly in the same vlan (frack-fundraising-codfw):
DHCPDISCOVER from 4c:d9:8f:a0:19:aa via 10.195.0.33
Here's the one from civi2001:
DHCPDISCOVER from 4c:d9:8f:aa:77:b4 via 10.195.0.1: network 10.195.0.0/27: no free leases
Papaul double-checked and the interfaces are in frack-fundraising-codfw as they should be. I confirmed the dhcp configuration and tested virtualbox, with the DHCP request routed via 10.195.0.33 it responds correctly.
