Is there a firewall or RADIUS server that can ping a third party web API when a new client/device connects to it?

I'm developing a check-in system that should know which devices just connected to a particular network and it would be great if the firewall software could send a ping to my web server including the devices MAC address.

Can pfsense or some other similar software allow this kind of notification?

Any acceptable firewall should be keeping logs, which you could just scan for source IP addresses. Keep in mind that you're only going to see MAC addresses for directly-connected LAN devices, and that's at a lower layer than IP, so most firewalls wouldn't log that.

As far as RADIUS, why would that be a factor? Are you using RADIUS in some way to authenticate LAN-side machines?

What is your desired end-state; what's your real goal?

We will have a captive portal which authenticates users for network access. But once the device has been accepted and given a lease, I still want to know whenever said device connects in the future. –  Mattias Mar 31 '11 at 21:12
OK - if you know the IP address of the device, you can trawl your firewall logs which should be capturing that. That's why I asked what your real goal is - perhaps you can edit your question with a use-case. –  mfinni Mar 31 '11 at 21:14
