Hello Neale Ranns, How libmemif is supposed to be used then ? Did you get a chance to look into use case above ? -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group. View/Reply Online (#17229): https://lists.fd.io/g/vpp-dev/message/17229 Mute This Topic:

Hello team, I have a setup where vpp is running with dpdk on two nics. I have added NAT and other configurations and hence vpp is working as router. I want to integrate my DPI application hence need to intercept packets. I have looked at libmemif and its icmp-responder applications. But I was
