hello, wrote some small path, which adds authorization with source ip. to patch: cd ./ser-0.8.14 patch -p1 < ser-0.8.14_ip_auth.patch add additional string column to subscribers: acc_ip ex. usage: www_authorize_ip("your_realm", "subscriber", "0.0.0.0") ) where "0.0.0.0" means that source ip will be taken from from msg structure. If you specify IP instead of "0.0.0.0" then it will be checked instead of one taken from msg structure. It would be equivelent to write src_ip != "source_ip_to_check" && !www_authorize("your_realm", "subscriber") and !www_authorize_ip("213.226.186.195", "subscriber", "source_ip_to_check") Antanas
