Hello friends! I got a new router, Huawei B310 4G (Orange, Romania). Wathever i try for port forwarding, it fails. I tried to put the IP of the respective machine in DMZ, I created a virtual server, I also created a DDNS (no-ip) and it still doesn't work.. I tried it on all devices (PC - LINUX/WINDOWS, Android phones) but it still says on canyouseeme.org and other sites the same thing (the port is closed) and I also tried ports 443, 4444, 80, 555. What am I supposed to do? Should I use a Static IP? Should I connect the PC to the router via Ethernet cable? Please, help.
Thanks in advance!
