摘要
The invention relates to filtering of telecommunication in the network, in which the devices connected to the network have device-specific filtering rules. A firewall component (FW) is arranged in the telecommunication network in such a manner that all the telecommunication goes through the firewall component (FW). The firewall component (FW) is connected to a database server (DB), to which the filtering rules are saved. It is possible to connect several firewall components (FW) to the same database. The firewall component (FW) retrieves from the database (DE) the sender's and the recipient's filtering rules based on unique identification information. In addition, from the database (DE) it is possible to retrieve the filtering rules of the service provider or additional filtering rules, e.g. group-specific rules. Each rule is handled separately, and in case the telecommunication is in accordance with all the rules, it is transmitted further.
