 Some modules such as rlm_sql_postgresql can have their timeout set via an alternative

+### rlm_radius
+
+The `radius` module has taken over much of the functionality of
+`proxy.conf`.  See `raddb/mods-available/radius` for documentation and
+configuration examples.
+
+The `radius` module connects to one home server, just like the
+`home_server` configuration in v3.  Some of the configuration items
+are similar, but many are different.
+
+The module can send multiple packet types to one home server.
+e.g. Access-Request and Accounting-Request.
+
+This module also replaces the old 'coa' and 'originate-coa'
+configuration.  See also `fork` for creating child requests which are
+different from the parent requests.
+
+Unlike v3, the module can do asynchronous proxying.  That is, proxying
+where the server controls the retransmission behavior.  In v3, the
+server retransmitted proxied packets only when it received a
+retransmission from the NAS.  That behavior is good, but there are
+times where retransmitting at the proxy is better.
