I have Wamp 3.0.6 on Windows 10 (64-bit)
Apache/2.4.23 (Win64) PHP/5.6.25 - Port defined for Apache: 80
I am not getting ACKs to TCP Syn requests on port 80, even on my LAN. My Wamp is completely green light. I can browse to my localhost/www pages.
I have collected a PCAP

My destination of my WAMP is 192.168.1.129
My httpd apache is PID 4996 and it is indeed listening.
$ netstat -ano | grep 4996
TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 4996
TCP [::]:80 [::]:0 LISTENING 4996
What could be my next steps? I have an out-of-the-box windows 10 distro on a brand new server -- I have not installed any additional ACL or malware software.
Any direction would be much appreciated.
