LEAP Through a Firewall

When a client tries to leap authenticate how is it sent out? UDP, TCP, RDP and what port numbers does it run on?

Thanks

Re: LEAP Through a Firewall

I couldn't find it in RFC 1700 but I think the easiest way is to attempt the authentication while logging the traffic on the firewall. Then look at the log and see what ports are being denied.. open them up and try again. Anyone know the actual ports/protocols used? I'd be interested in knwoing this as well. Thanks.

Re: LEAP Through a Firewall

When leap client has to get authenticated, the packet goes to AP (Access Point), and the AP sends it to the Radius server. So following ports are used;

Radius UDP 1645/1646 or 1512/1513
