Salman, What you're doing sounds completely normal. What controller are you using?
Also, if you're using wireshark to dissect the packets, the IPs are a bit confusing -- you're seeing the IPs of the data packets embedded in the packet_in's, not the IPs of the outer transport layer packets. If you explore deeper into the packet, you should be able to verify this. - Rob .
