Hi Neale, The ABF is ACL based matching and forwarding plugin right. This would allow one to match a packet with ACL and forward it on a configured outbound interface.
My case is different, I don't want to match ACL and forward packets out on an interface. I want the packet matching a certain SRC IP range to be sent to my new plugin (in this case *XYZ *) which would do further processing specific to our product. For example, if IPSec traffic is originating from UE, we see the packets flow through these nodes. After ESP and GRE, the inner packet src IP is that of the UE. Is it possible for graph node *XYZ *to request for an IP packet matching certain SRC IP? UE ----------> [ESP4_decrypt----IP----GRE_Input-----IP----*XYZ*-----IP-----Interface]---------> internet host Regards.
