Firepower 1010 Port Forward Struggle

[Edgieace]

Hi guys,

I have been struggling on this for days, I have a nginx web app running on my server(192.168.10.5) that I am trying to port forward it to be accessible on the internet. I was able to do a port forward easily if I were to do a direct connection from my computer -> switch -> ISP modem.

But if I put it behind the firewall (Firepower 1010 Series) I am struggling it always says that my port is closed.

The network diagram look like this(with only the vlan10 that is shown): 

this is the route table:

Access-list:

NAT:

I also encountered something that might be a factor on the problem, is that when I ping the firewall outside interface(192.168.1.8) from my server (192.168.10.5)  it result me in time out but I can ping the gateway(192.168.1.1) and other device that are connected on the ISP modem.

If I ping inside the firewall cli, I can ping everything all right.

Hi guys, I was successfully did a port forward on my web app, and it's all working now. Thank you for the solutions you provided me it helps a lot on both my NAT and ACL configurations, on my last problem there seems to be a problem with my ISP so I had them do a bridge mode on my modem and put a third party router where I could port forward peacefully, and everything works now. Thank you.
