1. Check if your DNAT rule settings are like in my scrshot 1. Also check is the rule status in enabled/green state (dummy I know, but it happens to me all the time...[:)]). 2. Enable Log traffic in automatic created Firewall rule. 3. Try to telnet from the outside to the public UTM address on port 8090. 4. Open the live Firewall log.
If you see green lines like in my example (scrshot 2), then the problem is related to the internal web server.
