Yes. It's something with the Start accounting packet on Cisco NAS's. You have to
configure the Cisco NAS for sending an "update" packet:
This is the Start packet:
Mon Aug 28 00:11:08 2000
NAS-IP-Address = xxx.xxx.xxx.xxx
NAS-Port = 98
NAS-Port-Type = Async
User-Name = "xxxxxx@xxx"
Called-Station-Id = "xxxxxxxxx"
Calling-Station-Id = "xxxxxxxxx"
Acct-Status-Type = Start
Acct-Authentic = RADIUS
Service-Type = Framed-User
Acct-Session-Id = "0000A5A7"
Framed-Protocol = PPP
Acct-Delay-Time = 0
Timestamp = 967414268
And this is the Update packet, where you can see the IP address:
Mon Aug 28 00:11:11 2000
NAS-IP-Address = xxx.xxx.xxx.xxx
NAS-Port = 98
NAS-Port-Type = Async
User-Name = "xxxxxx@xxx"
Called-Station-Id = "xxxxxxxxx"
Calling-Station-Id = "xxxxxxxxx"
Acct-Status-Type = Alive
Acct-Authentic = RADIUS
Service-Type = Framed-User
Acct-Session-Id = "0000A5A7"
Framed-Protocol = PPP
Framed-IP-Address = 212.7.51.180
Acct-Delay-Time = 0
Timestamp = 967414271
