(RADIATOR) Radiator adding attributes when forwarding a packet

[Victor Stanescu]

Hello,

I have configured radiator to forward the packets to a remote radius (gnugk), so 
one of my customers is able to do its own billing.

Radiator receives a packet like:
NAS-IP-Address = 212.146.67.10
NAS-Port-Type = Async
User-Name = "0214100100"
Called-Station-Id = "268307432"
Calling-Station-Id = "0214100100"
Acct-Status-Type = Start
Service-Type = Login-User
cisco-h323-gw-id = "h323-gw-id=gw01-brv1."
cisco-h323-conf-id = "h323-conf-id=B3390F0F 44BE05B3 0 429A514C"
cisco-avpair = "h323-incoming-conf-id=B3390F0F 44BE05B3 0 429A514C"
cisco-h323-call-origin = "h323-call-origin=answer"
cisco-h323-call-type = "h323-call-type=VoIP"
cisco-h323-setup-time = "h323-setup-time=16:26:35.162 EET Mon Mar 10 2003"
Acct-Session-Id = "0000057D"
Acct-Delay-Time = 0

When it forwards the packet, it has a new attribute inside:
NAS-IP-Address = 212.146.67.10
NAS-Port-Type = Async
User-Name = 0214100100
Called-Station-Id = 268307432
Calling-Station-Id = 0214100100
Acct-Status-Type = Start
Service-Type = Login-User
h323-gw-id = gw01-brv1.
h323-conf-id = B3390F0F 44BE05B3 0 429A514C
Cisco-AVPair = h323-incoming-conf-id=B3390F0F 44BE05B3 0 429A514C
h323-call-origin = answer
h323-call-type = VoIP
h323-setup-time = 16:26:35.162 EET Mon Mar 10 2003
Acct-Session-Id = 0000057D
Acct-Delay-Time = 0
! h323-return-code = \076\154\240\230

I have sniffed the connection, and confirmed that indeed the cisco gateway does 
not send the attribute, and it appears from nowhere in the packet sent by 
radiator to the remote radius server.

Any idea what causes this behaviour?

The configuration is pretty plain, it does only <Handler> matching for packets, 
so it forwards only some packets, but it does no rewriting of the packet or 
things like this.
