I've got a fiber router from my IP, but they lock the access (Web GUI) to it.
The private IP address class (LAN) of it is 192.168.254.1...
And it has a port forwared from any port to 192.168.254.2
So i can configure my own OpenWRT router as a DMZ - when i use the static IP 192.168.254.2 on its WAN port.
Then i'm able to configure a port forward, e.g. to port 80 from:
-> public ip xxx.xxx.xxx.xxx -> 192.168.254.2 (fiber router) - > 192.168.1.1 (my own OpenWRT router) -> 192.168.1.171 (win10 machine with apache)
BUT: When i try to enter the public ip xxx.xxx.xxx.xxx in browser (same computer where apache on port 80 is runnnig), there is no response on port 80.
When i use tor browser, a vpn connection or a separte internet connection on my mobile phone, port 80 gives me a reponse...
That problem is really really strange... does somebody have a hint for me? May be the problem on my own OpenWRT router or on the fiber router of my ISP?

Routenverfolgung zu xxx.dyn.ftth.fcom.ch [yyy]
über maximal 30 Hops:
1 <1 ms <1 ms <1 ms OpenWrt.lan [192.168.1.1]
2 4 ms 8 ms 3 ms xxx.dyn.ftth.fcom.ch [yyy]
yyy = my public ip
xxx = my public ip written in a reverted way
port 80 on xxx.dyn.ftth.fcom.ch does also not respond on my own computer. (same computer where apache is running on port 80), but i also get a response from tor browser, with a vpn connection, from mobile phone. (so same as described before)
Then OpenWRT version i use is 18.06.1...
Thank you very much.
