 Subject:  Allocate a fixed IP for PPTP-VPN user (RADIUS)
 Date:  Thu, 25 May 2006 10:51:16 +0200
Hello,

I'd like to allocate a fixed IP for a special PPTP-VPN users on M0n0wall 1.22. 
The authentication is against RADIUS.
The server (freeradius on Debian Sarge) runs pretty good and the 
authentication works very fine. The only thing that i wish is to allocate 
special users fixed IPs.

The M0n0wall-PPTP-Server's IP is 192.168.40.254
The PPTP-Network is 192.168.40.96/28

M0n0wall gets the right reply access-package for the user "foo" with password 
"bar":

radtest foo bar localhost 1645 foobar
Sending Access-Request of id 67 to 127.0.0.1:1812
        User-Name = "foo"
        User-Password = "bar"
        NAS-IP-Address = rossoll
        NAS-Port = 1645
rad_recv: Access-Accept packet from host 127.0.0.1:1812, id=67, length=56
        Idle-Timeout = 86400
        Framed-Protocol = PPP
        Service-Type = Framed-User
        Framed-Compression = Van-Jacobson-TCP-IP
        Framed-IP-Address = 192.168.40.100
        Framed-IP-Netmask = 255.255.255.255

I found in list-archive, that M0n0wall 1.22 supports the attribute 
"Framed-IP-Address" [1]. Is the Attribute "Framed-IP-Netmask" not supported? 
When I delete the "Framed-IP-Netmask" Attribute, it's the same effect.

Thanks,

Ekkart Bahr
