So I want to create a port release for Minecraft on my Fritzbox, but it didn't work, so I reported it to the support team. You wrote that to me after all
"The 7490 is in ATA mode behind another router.
The front router will also have a firewall or NAT, so the ports there must also be forwarded to the FRITZ! Box and point to the WAN-side IP of the 7490.
In the case of the data you have sent, this is the IP 192.168.0.10, but it can't be seen whether this changes.
In other words, it is not enough to only enable port forwarding in the FRITZ! To set up the box, you would also have to do the above Make settings on the upstream router. "
You said that I should contact the manufacturer, but I don't understand what you meant.
Do you have 2 routers at all?
And what exactly did not work?
Yes, I have 2 routers, one of which is a Hitron and the other a FRITZ! Box. I tried a port tester to see if the port was open and it told me that the firewall was preventing the port from coming through.
Why do you have that? Why don't you just take the Fritz Box?
They are connected to each other so I can't access both individually
That doesn't answer my question. Are there technical constraints to use two routers in cascade?
Yes there's
This is bad.
What can I do now?
