Dear All, I'm having some trouble asking my freeRADIUS-2.1.10 server (Linux, x86_64) to correctly proxy CoA and Disconnect-Request packets. I am generating Disconnect-Request packets from my "network_control" machine (172.16.3.2) to the freeRADIUS server at 172.16.3.11 using: cat packet.txt |radclient -x -d /etc/raddb 172.16.3.11:3799 disconnect secret1 where packet.txt contains the following AV pairs: Acct-Session-ID = '819026ec' NAS-IP-Address = '172.16.3.60' User-Name='testuser@test.com' I was hoping that the requests would be proxied to "pppoe_one" at 172.16.3.60. The "network_control" machine receives a Disconnect-Ack from the freeRADIUS machine but the packet is not being retransmitted to "pppoe_one". Output from 'radiusd -X' is: rad_recv: Disconnect-Request packet from host 172.16.3.2 port 34463, id=100, length=66 Acct-Session-Id = "819026ec" NAS-IP-Address = 172.16.3.60 User-Name = "testuser@test.com" server coa { # Executing section recv-coa from file /etc/raddb/sites-enabled/coa +- entering group recv-coa {...} ++[control] returns noop ++[ok] returns ok # Executing section send-coa from file /etc/raddb/sites-enabled/coa +- entering group send-coa {...} ++[ok] returns ok } # server coa Sending Disconnect-ACK of id 100 to 172.16.3.2 port 34463 Finished request 0. As far as I know, I have followed instructions documented in sites-available/coa as well as reading a few other relevant posts on this list. I wonder if anyone has any advice? Relevant extracts from my configs are listed below.
