Hi, i am currently trying to code a little netfilter plugin, to be placed into the bridge forwarding path. In such plugin, i would like to test if a packet is: - unicast - multicast - broadcast The starting condition is that the bridge has no knowledge of the IP configuration of the sending and receiving stations. It does not know about their netmask e.g. I have tried the following function (from 2.6 kernel): inet_addr_type(u32 addr), but it always return RTN_UNICAST, and never RTN_MULTICAST, RTN_BROADCAST. For example, for this address: 10.255.255.255 it returns RTN_UNICAST. How could the bridge decide in which class is the destination IP of a skb, and what is my error? Thx in advance. LOUIS
