now when i run the cli

redis-cli -h 192.168.100.4 -p 6379

open lib/Makefile
change
#FF_LOOPBACK_SUPPORT=1 to
FF_LOOPBACK_SUPPORT=1,

open LOOPBACK SUPPORT, make it
I'm not sure if it's possible, since I developed this loopback feature specifically for the LD_PRELOAD mode, but we can certainly give it a try

tried no luck. do i need to add any arp in ff_route or ff_arp??

In other way how can I test this nginx. Basically my nginx is running in f-stack space now how can I send request to it. Either from my system or from another system on same network.
Even I have no clue how this communication works for any dpdk based app. Is there any documentation available for this
