[RADIATOR] proxying POD reply packets

[Michael]

Heikki, to answer your questions at bottom

I wonder if you have a (very) old Radiator or more likely, a
configuration that causes NAKed messages to be rejected.

I'm using v4.10 so it's not old.  I do however have a quite complicated radiator configuration.  Mainly, i inject POD's and COA's into radiator rather than sending directly to devices because i have many different cisco devices, some using different commands to accomplish the POD and COA.  radiator applies the necessary commands for the given device before proxying.  Also, i wanted these requests to be logged.  So, my complicated config determines what device the request needs to go to and sends, and then it converts the POD and COA packets to accounting packets using scripting, then sends to my accounting handler and that POD/COA request is logged.  So yes, i will have to review my config.

For now though, adding the NAKed requests to the list in the code i described does make sure the reply packets coming back from the nas's are proxied to the radpwtst client.

There's probably a better way of accomplishing this for sure.  I'll look into this further
Thanks.


Michael
