Hello all, How can I prevent to be flooded by RADIUS packets from an IP address? At first, I tried to deny the 1812/1813 ports from all IP's which does not have any RADIUS relation to my RADIUS Server using access lists. But then I found the case, where I have to open the Ports to an external downstream RADIUS proxy server, which has to respond to my RADIUS requests. This external server has also to send his UDP packet to my 1812/1813 port.
What do I need to prevent the case, where somebody has hacked the external RADIUS server and intentionally starts flooding my server or this external sever simply runs amok? Thank you. Regards Stefan - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
