Hi, I'm working through setting up FreeRADIUS to behave as a DHCP Server so that it can read and respond to DHCP Packets (including Option 82 info). I'm making progress - however I am facing a few roadblocks that I would like some guidance on if possible. *Packets forwarded from an internal network which are translated out to us and carry a DHCP-Relay-IP-Address* DHCP Requests that are being sent to us include a Relay-IP-Address - and implicitly the DHCP module seems to use this as an authority and attempts to return the packet to the Relay IP, not the source of the packet. I was able to comment out in the source (3.0.12) - "modules/proto_dhcp/dhcpd.c" on line 497 (where it sets a new destination IP address) - and the packet was returned to the originator. Obviously this is not the way I should be doing this - so any suggestions are welcome. *DHCP IP Addressing from SQLIPool* I have the radippool (via dhcp_sqlippool) process able to extract an IP address based on the Circuit ID (Option 82) contained within the DHCP Packet. The challenge I have, is the IP addresses I am allocating (for the same provider, but we will also have multiple providers who use our system) - has different gateways based on the location of the service and the IP allocated. From what I can ascertain looking at the source code, the DHCP Pool functionality presently only deals with the returning of the Framed-IP-Address. Looking at "modules/rlm_sqlippool/rlm_sqlippool.c" (line 580) - there is an object called 'inst' with a property called framed_ip_address. This is used to build a 'vp' and adds it to the reply. How would one go about providing database driven gateway/dns settings? Is there a way? Or is the only option to add support for additional properties in the code for this? (I would need to isolate where the framed_ip_address is mapped to Framed-IP-Address to follow the similar behaviour. Hope you can help! Thanks Martin.
