Hi Alan , Just want to add Current configuration in originate-coa file is below . It is the default configuration i did not change it. home_server localhost-coa { type = coa # # Note that a home server of type "coa" MUST be a real NAS, # with an ipaddr or ipv6addr. It CANNOT point to a virtual # server. # ipaddr = 127.0.0.1 port = 3799 # This secret SHOULD NOT be the same as the shared # secret in a "client" section. secret = testing1234 # CoA specific parameters. See raddb/proxy.conf for details. coa { irt = 2 mrt = 16 mrc = 5 mrd = 30 } } And in the clients.conf i did not enable the "# coa_server = coa". Because i did not want the freeradius server recieve the COA Request. I hope my understanding is right.
