Configuration for Cisco DSL Users
I'm new both to freeradius and the *nix operating system. I have successfully implemented freeradius for users dialing in through Portmaster3 Access Servers using FreeRadius 1.0.1-1 on Fedora. I am currently authenticating DSL users locally on a Cisco 7206VXR Router. I would like to authenticate the DSL users on the FreeRadius Server, but attempts have been unsuccessful. The Accounting works. Even now with DSL Users set to Auth locally on the Router, Radius is faithfully logging the activity. With Radius Auth, the DSL modem will not connect and I get no entry in the Radius accounting log. AAA Debug is virtually Identical to the Local Auth output! The only difference was the line "Method=local" changed to "Method=Radius". Both log entry sets have Status = PASS and both show the virtual-access change to up! So now I'm thinking the AAA/Radius is working but I have a communications issue. When a DSL user authenticates locally, he then gets an IP address from the local pool on the Cisco. When the same DSL User authenticates on Radius, all communication seems to stop. Here are the relevant config sections from the Cisco. aaa new-model aaa authentication login default line [*currently set to local] aaa authentication ppp default group radius local [see*above] aaa authorization network default group radius local aaa accounting delay-start aaa accounting network default start-stop group radius interface Loopback1 description DSL ip address 206.206.89.1 255.255.255.0 secondary ip address 206.206.88.161 255.255.255.240 secondary ip address 206.206.86.1 255.255.255.0 interface Virtual-Template2 description DFN NEW Template ip unnumbered Loopback1 ip mroute-cache peer default ip address pool OsoGranDSL OsoGranDsl2 ppp authentication pap radius-server host [omitted] auth-port 1645 acct-port 1646 radius-server host [omitted] auth-port 1645 acct-port 1646 radius-server key [omitted] Heres an example entry from my users file: username Auth-Type := Local, User-Password == "omitted" User-Service-Type = Framed-User, Framed-Protocol = PPP, Framed-Address = 255.255.255.254, Framed-Netmask = 255.255.255.255, Framed-Routing = Broadcast-Listen, Framed-Filter-Id = "std.ppp", Framed-MTU = 1500, Framed-Compression = Van-Jacobsen-TCP-IP I think I'm close, and I have a hunch the users file settings that work for PortMasters may not be good for Cisco. Any suggestions or sample configs would be appreciated. Bill Green Dfn Systems
You will need to do debug ppp negotiation to see is IP address allocation the problem. If it is, you can always use Freeradius ippool (or sqlippool in latest versions) to alocate IPs. Ivan Kalik Kalik Informatika ISP Dana 22/9/2007, "DFN Systems Office" <office@dfn.com> piše:
