SONICWALL TZ670 Web Server on DMZ not working
I am trying to access a webserver behind the Sonic TZ670 which connected to X7 interface of the Sonicwall. The ISP's router has been bridged to the Sonicwall so the sonic wall is acting as the LAN's gateway. When the web server is put on the LAN subnet, it works with the right access rule and NAT policy but when it's put on the DMZ it doesn't seem to work. Your help will be very much appreciated. Please see the attached network diagram.
