19.7 Legacy Series / Port Forwarding under Double NAT (with DMZ) not working
« on: November 14, 2019, 07:04:22 pm »
Hello!
I've recently setup a OPNSense box with two 10 gbit interfaces.
I've got a router that does not support bridge mode from a provider, that is unchangeable.
So I've given the OPNSense box a permanent DHCP IP and gave it DMZ rights.
The current network setup looks like this:
Routerbox: 192.168.0.0/16
OPNSense router: 172.16.0.0/12
Routerbox (Set OPNSense box as DMZ host) -> OPNSense box -> Webserver
I've tried to port-forward the Webserver using the traditional method but whenever i've tried to port-check the external ip, the connection is refused and there's nothing written in the logs. I have tried several guides since then but they've all failed me so far. I've been reading that it is not possible, so my question is, what am i doing wrong and if it is possible, can you please tell me how to do it?
