Recently setup a CentOS web server in DMZ, I initially setup the rules/policies manually but kept getting connection refused when trying to access the public IP through port 80 (opened), after failing to get it to work I deleted the rules and used the wizard to auto create the rules but after this still getting the same result, I can ping addresses outside the network etc and I can see data being sent and received through the rules.....but keep getting connection refused....I even went as far as disabling firewalld on the server etc but to no avail so I am thinking this is something to do with the sonic wall or the dmz setup...any advice is appreciated.
To clarify, I can ping the server from the LAN to the DMZ...but cannot access it externally via port 80...thats when connection refused.
