Issue With Port Forwarding (MX behind Att Router)

[EDIT]

Hi Team,

Running into a networking and/or firewall issue where I'm not getting http and https traffic for host on my internal LAN. My setup is as follows:

Previous working topology:

Edge router (att BGW210) <> Virtual switch <> Web Server

New topology not working:

Edge router (att BGW210) <> MX Firewall <> MS Switch <> Virtual switch <> Web Server

On my previous topology, only way it works if I setup port forwarding on the att router to the internal web server. However now that I've implemented the MX firewall and MS switch, can't get port forwarding to work. 

On my att router, I now have port forwarding http and https traffic to my MX firewall where I then configured port forwarding on the MX and set my web server as the destination LAN server.  Not sure what step I'm missing buy any guidance would be greatly appreciated. 

Note that I tried packet captures on the switch uplink where not seeing any http or https traffic being sent from the MX.

Do you see the the traffic an the mx wan.

You can also make packet captures  there

Thanks I found the issue and end up being unrelated to the setup. Confirming that my new setup now works.
