I have tried to run dpdk-nginx example as given instructions. dpdk and dpdk-ans running without error.

But when I try to execute ./objs/nginx I get following error.

Ignore these errors.

I have tried ab -n 30000 -c 500 192.168.20.30:80/

Benchmarking 192.168.20.30 (be patient)
apr_pollset_poll: The timeout specified has expired (70007)

I can ping to 192.168.20.30 IP from another VM

[bluenet13]

What is the ans startup log?

10.0.0.2 is configured in ans stack， no 192.168.20.30 IP address is configured in ans stack.
Why do you want to connect to 192.168.20.30?

[sachithmuhandiram]

this is just the log, I configured ans IP to 192.168.20.30 and tested with ping using using another VM. It was working. And even I tried with this default 10.0.0.2 IP, same result.
sorry, I forgot to update that part.

Get below output:

tcpdump on linux side, and share the captured file.
