Greetings,
I have my UTM running in bridged mode behind a Mikrotik router. I.e. the UTM is not doing NAT, DNS, or DHCP.
This works great, except for one thing: Web filtering blocks any traffic from my LAN addressed to port 80 or 443 on any host on my LAN when going via the public IP. Just these two ports. No other forwarded ports are blocked.
Access by local IP works fine for all ports.
My public IP is 176.10.x.x and the local IP of my web server is 192.168.2.2
So from a host on the local network,
http://192.168.2.2 or https://192.168.2.2
works, while
http://176.10.x.x or https://176.10.x.x
does not.
I can forward ANY WAN port to ANY port except 80 or 443 on ANY host on the LAN and it works fine. But port 80 and 443 remain reachable from the WAN only, regardless of which host it is forwarded to.
If I switch web filtering off completely, the problem disappears. What sort of exceptions do I have to set up?
