Hi, I'm using a system (openvpn) with 'radiusplugin' to let FR authenticate users and manage IP Pools. Openvpn sometimes needs to renegotiate the connections and thus sends authentication requests while the connection is still active (with an already assigned IP address): this causes FR to assign a new IP address from the pool (which seems normal since FR has no way to know this is a renegotiation). I'd like to patch the openvpn-radiusplugin so that an extra attribute is sent in the Access-Accept packets so that FR will be able to differentiate Initial and Renegociation Access-Accept requests and only assign new IP address from the pool on Initial Access-Accept requests. Do you know a standard Radius attribute that could be used for this ? As far as you know, are there other NASes using such a quirk ? Does this make sense ? Thanks in advance, Thibault
