    • The present invention relates to a method and an apparatus for providing internal server. The method comprises: matching relevant information carried by a message exchanged between an internal network and an external network with corresponding relationship information between external characteristic information and internal characteristic information of the internal server configured in a mapping table, wherein the external characteristic information comprises an external address and an external port of the internal server, and the internal characteristic information comprises an internal address and an internal port of the internal server; and processing the message according to a matching result. According to the present invention, WEB server and FTP server in the LAN can be easily provided without occupying too much valid IP addresses, thus, the present invention saves limited public IP addresses resource. Furthermore, the present invention implements port-level support to the internal server, and guarantees the security of network equipments.
    • 本发明涉及一种用于提供内部服务器的方法和装置。 该方法包括:将在内部网络和外部网络之间交换的消息携带的相关信息与在映射表中配置的外部特征信息和内部服务器的内部特征信息之间的对应关系信息进行匹配,其中外部特征信息包括外部 地址和内部服务器的外部端口,内部特征信息包括内部服务器的内部地址和内部端口; 并根据匹配结果处理消息。 根据本发明,可以容易地提供LAN中的WEB服务器和FTP服务器,而不占用太多有效的IP地址,因此本发明节省了有限的公共IP地址资源。 此外,本发明对内部服务器实现端口级支持,保证网络设备的安全。
