problem logging radius requests to NPS (IAS)

RouterOS General
1

Hi all.
I use NPS (the old microsoft IAS) as radius to AAA hotspot users from a miktorik device.
The login requests caming from the hotspot contain the parameter:

  • AttributeNasPort: 2154823689
    Type: NAS Port, 5(0x5)
    Length: 6 (0x6)
    NasPort: 2154823689 (0x80700009)

NPS log this into a SQL table sending an XML to the database.
The xml is created using data_type = integer but when the NPS log the request I have an overflow because 2154823689 is too much (if NPS cannot log neither authorize the user).

Is it possible to send from hotspot requests using a NasPort that I can convert as integer ?

thanks
