I use the UTM9 also for webserver protection.
So i have several web server(s) running on different devices.
I discover when under the Virtual server configuration the option "Enable HTML rewriting" is selected. the firewall drops a lot of packets coming back from the web server to the UTM device.
for example
Default DROP
TCP Internalweb-server:443 →LAN IP proxy:50562
