hello everyone. i am running a FRITZ!Box Fon WLAN 7270 v3 with FRITZ!OS 05.53 and Firmware version: 74.05.53
i am facing an issue with portforwarding. i do need to have 4 ports opened in a machine (55522, 55588, 55590, 55599).
aparently only the first two seem to be opened. the last two are not. in the print screen i do not have 55599, due to testing.
as you can see in port check the 55522 works fine
the problem is with the 55590
i have even tried to factory reset the fritzbox. still the same procedure. the problem is that the fritzbox is only portfrwarding these 2 ports, and nothing else.
i have tried a different vendor for router (mikrotik 750, cisco 877) and i did have a success. any ideas what it might the solution be?
