Hello all, I am testing IP_BINDANY functionality with a small C program. I can bind to a foreign (non existing) address, and syn packets are being sent with the bound source IP address and port. Return (ACK) packets are reaching the host (I can see the SYN-ACK packet in tcpdump), but the third packet in TCP handshake is not getting generated. It looks like the second SYN-ACK is not getting accepted by the kernel.
