Hi Vijay, VPP’s tcp implementation does not support keepalives so I’m assuming you’d like to intercept/drop packets that flow through vpp. As far as I know, there’s no straight forward way to do that. So you might have to implement a tcp connection tracker and some heuristic to detect keepalives or a transparent tcp proxy.
