5506X Firewall not working

[xxturboxx05]

Before I say anything, I would like to say that I just started using packet tracer and barely know how to use it thanks to my professor being bad at teaching. Now to my problem, my firewall is not allowing packets to go through in or out and I have been wondering why but I can't fix it. I added rules to allow transfers of data through it but it still won't let anything in or out so I'm left confused

 Seems your problem goes byond firewall. Your DMZ server IP address is wrong. They need to be on the same range as the firewall DMZ interface. 

 The connection between the Firewall on outside interface and the Router1 seems not to work. The interface on the router side, is not good. I believe you should take a different interface.  You probably installed module interfaces on the router and may took a wrong module. 

  Use NAT on the firewall only if your professor strictly asked you to. You dont need NAT. 

Your firewall is protected with password.

I have worked a little bit on your project but I had to replace your firewall as I dont have the password.

I had to make some changes on the routing part and on the router1 config. For now, you can ping from the PC in the green area to the DMZ and access the web server.

The new firewall I added to the topology does not use NAT. It only have route and Access List, for simplicity. 

The router1 must have route pointing to the DMZ network using the firewall as gateway. This very same route must be advertised on the RIP protocol in order to the other router know how to reach the DMZ. 

You can check all that on the file attached.
