Re: different eap/tls config for different interfaces
Mike, Sounds good, thanks for the info. Just curious: In the dual eap-tls configuration that you mentioned in the second paragraph, how would the radius server know which one to use for a given client? thanks! ----- Original Message ----- From: Michael Griego <mgriego@utdallas.edu> Date: Friday, August 5, 2005 11:34 pm Subject: Re: different eap/tls config for different interfaces
After I'm done with the rlm_eap_tls rewrites and rlm_eap updates, there will be functionality to have multiple EAP submodules of the same type with different configurations. With this, you'll be able to force the use of a specific EAP type instance by its instance name.
In the meantime, if you want to avoid bringing up two servers, you *can* configure two EAP module instances, each with a different tls submodule configuration. Force the Auth-Type to the EAP module with the correct tls configuration based on your criteria. I've used this scenario in the past.

Oh...duh...that makes sense. Should have considered that. I have since tested the behavior of the scenario I described, and Alan's on target. Doesn't really seem to matter which interface I enter on, or which common-name I use. Seems to work either way.
thanks for the help!

No. FreeRADIUS supports only 1 TLS module at a time.
What Alan forgot to mention is a solution.
If you run two copies of the Radius server, with one bound to either a different set of ports, or one to each IP, you could have separate configs. -kb -- Kris Benson, CCP, I.S.P. Technical Analyst, District Projects School District #57 (Prince George)

By its Client-IP-Address attribute or NAS-IP-Address attribute. Also, you can use the Packet-Dst-IP-Address attribute if you're certain that the clients are split up by interface. You can match up based on incoming interface like you were thinking about doing with two different servers. So, if your server is listening on 10.0.0.1 and 10.0.1.1, and your EAP modules are named EAPauth1 and EAPauth2, you could do: DEFAULT Packet-Dst-IP-Address == 10.0.0.1, EAP-Message =* "", Auth-Type := EAPauth1 DEFAULT Packet-Dst-IP-Address == 10.0.1.1, EAP-Message =* "", Auth-Type := EAPauth2 This functionality may only be CVS snapshots, though. I'm not sure as I haven't looked to see if it exists in the production releases. --Mike ragan_davis@colstate.edu wrote:

Hmm... I should update the EAP code so it sets Auth-Type to not EAP, but to it's instance name, if that exists. That will help this kind of configuration. Alan DeKok.
I was gonna do that as part of my updates, but if you want to do this, be my guest. :) --Mike Alan DeKok wrote:
