Hello list, I run a very simple architecture for broadband access with 2 routers, 2 radius proxies and 2 radius home servers. On the side of this architecture I run a homemade script that sends PoD directly to the two routers and everything works fine. I would like to change the direct access to the routers and have all my radius messages go through the 2 proxies, including the PoD. I have upgraded in 2.1.12 because of a bug in CoA proxyfication and now the PoD are handled correctly, sent to the routers through the proxy ! But there is a problem : the two cisco routers don't support the Proxy-State attribute and send me a very clear message : fgabut@savon:~$ cat toto | radclient -x a.b.c.d:3799 disconnect toto1234 Sending Disconnect-Request of id 138 to a.b.c.d port 3799 NAS-IP-Address = x.x.x.x User-Name = "xxx@nautile.nc" rad_recv: Disconnect-NAK packet from host a.b.c.d port 3799, id=138, length=47 Reply-Message = "No Matching Session" Error-Cause = Invalid-Request The debug message I have on the router is : Apr 28 23:42:29.980: POD: a.b.c.d Unsupported attribute type 33 for component Apr 28 23:42:29.980: POD: a.b.c.d user xxx@nautile.nc 0.0.0.0 sessid 0x0 key 0x0 DROPPED Apr 28 23:42:29.980: POD: Added Reply Message: No Matching Session Apr 28 23:42:29.980: POD: Added NACK Error Cause: Invalid Request Apr 28 23:42:29.980: POD: Sending NAK from port 1700 to a.b.c.d/1814 I can't find any option to not use the attribute 33 (Proxy-State) in the process of matching the session on the router. So I guess the only solution left is to filter the Proxy-State directly on the exit of the radius proxy. The RFC3576 states that : When using a forwarding proxy, the proxy must be able to alter the packet as it passes through in each direction. When the proxy forwards a Disconnect or CoA-Request, it MAY add a Proxy-State Attribute, and when the proxy forwards a response, it MUST remove its Proxy-State Attribute if it added one. So I was wondering if there were any option to disable the add of the attribute Proxy-State when the radius server proxyfies a CoA request ? I think that the usual attr filter method won't fit there.
