Port forwarding not working on Huawei B535-232 4G LTE router for ssh connection

Question

I have a Huawei B535-232 4G LTE router with the following configuration:

• set ddns with NO-IP,
• set static ip of the server to which I want to connect remotely via SSH,
• set SSH port forwarding with: Wan port 8888 and Lan port 22 for server static ip.

I do not understand why I can not connect, the port 8888 is closed,where I am wrong ?

Answer 1

I have the same problem with B535-333 model. I managed to open ports through Virtual Servers but I can only access them from "outside" (Internet) and not locally (LAN). I get a "Connection refused" error.

It looks like a firewall/NAT problem that should be fixed with a new firmware version.
