Network Traffic Analysis and Redirection

The main goal of this RFP is to design specific software for Ubuntu 16.04 for handling the traffic of two Gbe ports (LAN and WAN) which buildup a link. The traffic from the LAN port should be first analyzed using some filtering rules upon MAC source/destination addresses and IP source destination addresses and some protocols like TCP/UDP/HTTP/RTP/…. This analysis decides which portion of the incoming traffic is relayed directly to the corresponding physical WAN port without any change while the rest of the traffic should be redirected to a hardware co-processor for making some changes before it is passed to the corresponding physical WAN port. As the link works in full duplex mode, the above process should also be performed for the incoming traffic of the WAN port to the corresponding LAN port.
