So I never thought that I need to use "DHCP-Server-IP-Address" for the TFTP server (which is not the same as the dhcp server at our site).
What should work is, in the virtual server "listen" section, set the ipaddr or src_ipaddr to that of the DHCP server. Then in your policy set the value of &reply:DHCP-Server-IP-Address to be the TFTP server. Note, in FreeRADIUS v3, all DHCP options have a DHCP- prefix - this is to distinguish them from RADIUS attributes. In FreeRADIUS v4, virtual servers operate in a protocol name space, so those prefixes are removed, making this particular option less confusing - it does not refer to the "DHCP server IP address", but rather the DHCP option "server IP address" Nick -- Nick Porter
