[serusers]: trusted table(permissions module)

Hi All I made an entry "10.25.119.156, any, ^sip:.*$" into trusted table so that any packet sent from 10.25.119.156 would be trusted by SER and don't ask for its credentials. But SER is replying 407- proxy auth needed!! After this I tried with permissions.allow file: "ALL : "sip:mann@imsfw.de$"" but still no progress same response from SER. My ser.cfg entries: modparam("permissions", "db_mode", 1) modparam("permissions", "trusted_table", "trusted") modparam("permissions", "source_col", "src_ip") modparam("permissions", "proto_col", "proto") modparam("permissions", "from_col", "from_pattern") modparam("permissions", "default_deny_file","/usr/lib/ser/modules/permissions.deny") modparam("permissions", "default_allow_file","/usr/lib/ser/modules/permissions.allow") Is it correct? Please give your suggestions for the same. Thanks in anticipation Kamal Mann
