    • The invention proposes a method for controlling a connection between a first network node and a second network node, wherein the connection is controlled by a packet filtering function filtering packets such that a packet is discarded in case a source address and/or a destination address do not comply with a filtering rule, wherein the packet filtering function is configured at a connection set up, and at least one of the first or second network node is adapted to change its address, the method comprising the steps of informing the packet filtering function about the new address of the network node having changed its address, and updating the packet filter of the packet filtering function by using the new address of the network node having changed its address. The invention also proposes a corresponding network system comprising at least a network node and a packet filtering network element. Furthermore, the invention proposes a corresponding packet filtering network device.
    • 本发明提出了一种用于控制第一网络节点和第二网络节点之间的连接的方法,其中所述连接由过滤分组的分组过滤功能控制,使得在源地址和/或目的地地址做的情况下丢弃分组 不符合过滤规则,其中所述包过滤功能被配置在建立的连接处,并且所述第一或第二网络节点中的至少一个适于改变其地址,所述方法包括以下步骤:通知所述包过滤功能关于 网络节点的新地址已经改变了其地址,并且通过使用已经改变了其地址的网络节点的新地址来更新分组过滤功能的分组过滤器。 本发明还提出了至少包括网络节点和分组过滤网络元件的对应网络系统。 此外,本发明提出了一种相应的分组过滤网络设备。
