Yeah that's the problem. The documentation says that's what it does, but 
in fact it doesn't. Any Framed-IP-Address in radreply, superceeds and 
overrules any Framed-IP-Address from radgroupreply, and no operators 
change or alter that. I can put in a Framed-IP-Address in radgroupreply 
using = or :=, but it never ever overwrites Framed-IP-Address from 
radreply, and I can prove that group processing is happening because if 
I change it to +=, I then get both ip addresses in the reply. For example:


mysql> select * from radreply ;
+----+----------+-------------------+----+---------+
| id | UserName | Attribute         | op | Value   |
+----+----------+-------------------+----+---------+
|  4 | joe.user | Framed-IP-Address | := | 1.2.3.4 |
+----+----------+-------------------+----+---------+


mysql> select * from usergroup where GroupName = 'suspended';
+----------+-----------+----------+
| UserName | GroupName | priority |
+----------+-----------+----------+
| joe.user | suspended |        1 |
+----------+-----------+----------+



mysql> select * from radgroupreply where GroupName = 'suspended' ;
+----+-----------+-------------------+----+-----------------+
| id | GroupName | Attribute         | op | Value           |
+----+-----------+-------------------+----+-----------------+
|  6 | suspended | Framed-Netmask    | =  | 255.255.255.255 |
|  5 | suspended | Framed-IP-Address | += | 10.10.0.2+      |
| 10 | suspended | Framed-Filter-Id  | =  | "natroutes"     |
+----+-----------+-------------------+----+-----------------+
3 rows in set (0.00 sec)

radtest joe.user ididntpaymybill localhost 0 testing123 hello

Sending Access-Request of id 58 to 127.0.0.1 port 1812
        User-Name = "joe.user"
        User-Password = "ididntpaymybill"
        NAS-IP-Address = 255.255.255.255
        NAS-Port = 0
        Framed-Protocol = PPP
rad_recv: Access-Accept packet from host 127.0.0.1:1812, id=58, length=62
        Framed-IP-Address = 1.2.3.4
        Framed-IP-Address = 10.10.0.2
        Framed-IP-Netmask = 255.255.255.255
        Framed-Route = "40.0.0.0/16"
        Filter-Id = "natroutes"

So you can see both Framed-IP-Address from above. I got two because += 
added the 10.10.0.2 to the reply.

And now I'll change it back to := for show:

mysql> select * from radgroupreply where GroupName = 'suspended' ;
+----+-----------+-------------------+----+-----------------+
| id | GroupName | Attribute         | op | Value           |
+----+-----------+-------------------+----+-----------------+
|  6 | suspended | Framed-Netmask    | =  | 255.255.255.255 |
|  5 | suspended | Framed-IP-Address | := | 10.10.0.2+      |
| 10 | suspended | Framed-Filter-Id  | =  | "natroutes"     |
+----+-----------+-------------------+----+-----------------+
3 rows in set (0.00 sec)


radtest joe.user ididntpaymybill localhost 0 testing123 hello
Sending Access-Request of id 166 to 127.0.0.1 port 1812
        User-Name = "joe.user"
        User-Password = "ididntpaymybill"
        NAS-IP-Address = 255.255.255.255
        NAS-Port = 0
        Framed-Protocol = PPP
rad_recv: Access-Accept packet from host 127.0.0.1:1812, id=166, length=56
        Framed-IP-Address = 1.2.3.4
        Framed-IP-Netmask = 255.255.255.255
        Framed-Route = "40.0.0.0/16"
        Filter-Id = "natroutes"

Now you can see the Framed-IP-Address is 1.2.3.4 - it was not 
overwritten by the 10.10.0.2 from radgroupreply despite what the 
documentation seems to suggest and what you have stated. Can you suggest 
changes that will allow radgroupreply to set a Framed-IP-Address 
attribute that overwrites any set from radreply?
