Specific IP address for user

[richardp]

I am trying to configure a Cisco 3725 to give a particular dialin user a specific IP address and give all other users an IP address from the ip address pool. I have the ip address pool working but don't know how to give the particular user a specific address.

The users are authenticated by a RADIUS server

Here is part of the config:

interface Group-Async1

ip unnumbered Loopback0

encapsulation ppp

async mode interactive

peer default ip address pool dialin_pool

no keepalive

ppp authentication pap

group-range 65 88

!

interface Dialer0

ip unnumbered Loopback0

encapsulation ppp

no ip mroute-cache

dialer in-band

dialer-group 1

peer default ip address pool dialin_pool

no cdp enable

ppp authentication pap

ppp multilink

!

ip local pool dialin_pool 192.168.18.10 192.168.18.50

The right way to do this is put that IP address on the RADIUS server's profile for that particular user. Then have the router do aaa authorization against RADIUS in addition to aaa authentication, if you're not doing so already. Otherwise, the router will ignore the IP address specification.

How do you put the ip address in the profile? Is that framed-address?

For CiscoSecure ACS, the procedure is shown here:
