My team is evaluating freeradius if we can use it for a project. The requirements we have where we see freeradius can be a solution are the support of proxy, CoA and TLS. The network structure looks like: AP/Controller <-----LinkA-----> freeradius proxy <-----LinkB-----> cloud server LinkA uses RADIUS over UDP LinkB uses RadSec over TLS
From cloud server CoA messages will be sent over LinkB.
So far my team has verified the following working: 1 - Proxy + TLS 2 - Proxy + CoA But we are unable to verify Proxy + TLS + CoA, is this supported/possible with freeradius? If it is possible, our goal is to use the same LinkB connection/socket that was established by the first Access-Request for cloud server initiated CoA messages. Is it possible to configure the proxy to listen CoA messages via that same socket used for sending auth+acct requests? Thank you in advance for your help!
