Hi All, I've got a simulation environment in which I need to spoof source IP addresses. Basically, these "spoofed" addresses are virtual inside the simulator. I use raw sockets to build the packet and send them out on the wire. This worked fine in 2.4.x kernels (had to set rp_filter to 0 for the spoofed interface). In the 2.6.15 kernel (FC5-just installed), I get "Problem binding source address" error from init_socket. Ideas?
