Hello there to everyone.
I'm using freebsd for pptp server and I'm trying to setup a reeradius
ippoll feature working with fbsd.
I'm expiriencing problems with that, it dues to a problem that
(according to me) comes from a ppp userland tool.

I have setupped working freeradius+mysql and a pptp+ppp server, the
problem comes whe I try to get a dynamic ip from the freeradius(beacuse
ppp userland can't be used[or I'm mistaking? can ppp assign a dynamic ip
addres by itself?)
so this is the problem: 
when I try to test if it's working with radtest it goes something like
this:
radtest bla bla 192.168.0.100 1812 blabla

I got: 
rad_recv: Access-Request packet from host 192.168.0.100:3137, id=255,
length=55
        User-Name = "bla"
        User-Password = "bla"
        NAS-IP-Address = 255.255.255.255
        NAS-Port = 1812
modcall: entering group authorize for request 38

.... and I get an ip address assinged fomr the dynamic range:
rad_recv: Access-Accept packet from host 192.168.0.100:1812, id=99,
length=44
        Framed-Protocol = PPP
        Service-Type = Framed-User
        Framed-IP-Address = 192.168.12.192
        Framed-IP-Netmask = 255.255.254.0

BUT!!! when I try to connect trough the pptp (ppp implementation under
freebsd 4.9 using "set radius" in the ppp.conf I get this:

rad_recv: Access-Request packet from host 192.168.0.1:1421, id=109,
length=142
        User-Name = "bla"
        Service-Type = Framed-User
        Framed-Protocol = PPP
        MS-CHAP-Challenge = 0x35303437363836363834343734393632
        MS-CHAP2-Response =
0x010085a16d8c4d564e0b754f61fff6680efa0000000000000000032b2a37754168ca3fd20909891b617982a445a7e6670623
        NAS-Identifier = "valqk.upper.lan"
        NAS-Port-Type = Virtual


and after that:
rlm_ippool: Could not find nas port information. Return NOOP.
  modcall[post-auth]: module "access_pool" returns noop for request 35


As we obviously see, ppp is NOT seding the NAS-Port var when sending a
request to freeradius trought ppp... 

Is this some kind of bug and can anyone tell me why is this happenig???
I'd greatly appriciate any help!!
10x in advance!!!
