astf stateful traffic between two PCs running trex

[Foday Harris]

I am trying to run astf stateful traffic between two linux pcs running instances of trex. 

I tried using the script in the astf folder called http_advanced.py and changing the IP range to match the IP address on my two linux PC. 

I am having a problem where the server is responding with  [RST ACK]  am I doing something wrong?

By the way I don't have this issue when I run from the same PC port to port
