RADIUS Extensions for IP Port Configuration and Reporting

[Ali Arslan]

Hello all,

An ISP company uses NAT not to assign a distinct real IP to each user because of insufficient number of real IP.
And such ISP companies need NAT IPDR (Internet Protocol Detail Record) report with  following format:

User_Name | Private_IP | Private_IP_Port_Range_Start | Private_ IP_Port_Range_End |Real_IP | Real_IP_Port_Range_Start | Real_IP_Port_Range_End|Session_Star_Date | Session_EndUpdate_Date | Upload_Byte | Download_Bype | Session_Dsiconnect_Message | Session_State | Session_PVC | Service_Number | Session_Code

Here it is needed to get/set IP source transport ports allocated to a user but could not find attributes of such kind in freeRadius. In searching for that info i found RFC 8045  https://tools.ietf.org/html/rfc8045 which defines attributes IP-Port-Limit-Info, IP-Port-Range, IP-Port-Forwarding-Map.

Does freeRadius current version (3.0) has support for RFC 8045 ?

Are there any way to get the transport port allocated to a user when accounting session starts and write this info in radacct in a custom column so that we can use that port in IPDR reporting?

Thanks.
