    I set up on Router Port Mapping: Index Protocol Remote host Range of remote ports Local host Local port Status Action: 1 TCP / UDP 94 192.168.1.124 94 Enabled

    And when I check using www.whatsmyip.org/port-scanner/ it is without success because the result: Port 94 Timed-Out
    Maybe someone will help?

    What operator (Play, Orange, T-Mobile)? Check if the IP, e.g. on the website http://twojeip.wp.pl, coincides with the one obtained by the router. If not, it helps to enable the operator's fixed IP address service (I know, seems to be irrelevant).
    Appropriate connection parameters must also be set in T-Mobile. If I remember correctly it's apn data instead of internet.

    Aero2 (paid 30GB)

    IP from the website http://twojeip.wp.pl: 5.172.255.71

    From the router:
    Status
    SIM PIN status disabled
    LTE network mode (LTE)
    Connection Status Connected
    IP 100.82.16.121
    MAC 00: 1E: 10: 1F: 06: 03

    And the results of this is?

    Hm
    Will not move?
    An interesting thing because
    I have an IP Camera connected to my Router with the IP address 192.168.1.88 port 80
    and I can access it from the Internet (away and beyond the range of my local network)
    on an Android Tablet in the CamHI application.
    The tablet doesn't use my SIM card, but my friends' WiFi
    ???

    And the camera does not connect to an external service, which the device you use then connects to?
    What is the camhi application connected with?
    Maybe from the beginning, the port that is to be accessed from the outside, what should it be used for?

    Probably friends have external public IP.

    1. Friends do not have a permanent external IP
    2. The server is to provide the temperature and enable remote water heating
    3. What is CamHi connected with - I don't know
    4. It seems that the camera actually connects to the server from which I am probably getting the image from it:
    Data from "Setting" from Camera:
    Internet IP Address
    Main DDNS
    Server: hipcam.org
    Port: 80
    User name: Wszxp
    Password: ooooo

    Thanks :-)

    They do not have to because:

    The camera and the application connect to the "cloud". Teamviewer works on a similar principle.

    This cannot be done on a card with Aero. You can also use an intermediary server. Buy a VPN service and make sure that the device and the client connect to this server.

    Regarding the webcam: it looks like the webcam is connecting to hipcam.org and the tabla is also connecting to this service. In this case, hipcam.org is the middle ground, in short: the camera and the tablet meet on hipcam.org.
    Something like this can be achieved without having a public IP address or without having port forwarding capabilities using eg Hamachi.
    I conclude that the device that gives the temperature and controls the heating of water does not make it possible. Maybe it has the ability to set up an intermediary service, just like the camera?

    This device is my design based on ESP8266 plus a relay.
    I have "Clients" at home providing data at: http://silesia-eco.wroclaw.pl/EcoHome/DataShow
    and hence http://silesia-eco.wroclaw.pl/EcoHome/Board "Client" knows whether to turn the heating on or off. But this solution is limited by the frequency of data transfers - for me every hour.

    Since the data is on the server, it would be necessary to do something like a file / variable that would be read by ESP, e.g. by reading this file with variables, etc., and if there was a relay in it, he would do it.
    This is the case when the client is not visible on the network and cannot be sent data, but the server is visible and you can get a variable from it.

    See my post above. Client transfers data and receives commands from Server: http://silesia-eco.wroclaw.pl/EcoHome/Board
    The solution could be to increase the frequency of the Client's contact with the Server, but this solution does not seem optimal to me.

    By the way, returning to Kapera IP - how is this resolved?
    Is the webcam stream on server hipcam.org all the time?
    And how can you check it?

    So this is the data that controls the relay. Unfortunately, the server will not send them to the client because it cannot see them, so the client has to check them himself.

    Certainly not. The camera is logged into the server (with the login and password entered) and is waiting for "orders". When connecting the client to the server (you also need to enter the login and password), the server sends a stream request to the camera. The camera sends it to the server and the client receives it from the server.
    Something like chat on gadu-gadu, messenger, etc. All data "flies" through the server.

    If there is not much data, the server can be queried more often.
    The email client works the same. It checks the contents of the inbox every few minutes, and not like SMSs on the phone where you get it immediately (the phone must be constantly registered in the network anyway).

Topic summary

✨ The discussion revolves around configuring port mapping on a Huawei B593u-12 LTE router to access a home server from the internet. The user reports unsuccessful attempts to access port 94, which times out during scans. Responses suggest checking the public IP address against the router's IP, ensuring proper connection parameters with the mobile operator (Aero2), and considering the use of intermediary services like VPNs or cloud solutions. The user also mentions successfully accessing an IP camera via a different network, indicating that the camera connects to a cloud service (hipcam.org) rather than directly through the router. The conversation highlights the challenges of remote access without a public IP and explores potential solutions for remote server control and data transfer.

FAQ

TL;DR: Port mapping fails because the router shows 100.82.16.121 while the internet sees 5.172.255.71 (1 mismatch), and "Connection Status Connected" doesn’t mean you have a public IP. [Elektroda, waldemar.podgorski, post #16627158] Why it matters: If your LTE provider doesn’t give you a public IP, classic port forwarding won’t work—use VPN, cloud relay, or server-polling instead.

Quick-Facts

Quick Facts

How do I make a Huawei B593u-12 reachable from the internet over LTE?

If your router shows an internal-looking IP but websites show a different public IP, inbound access won’t work. The LTE operator is translating your traffic upstream, so port forwarding on the router has no effect. Use a VPN with a public endpoint, a cloud relay, or convert your design to poll an internet server instead. “Connection Status Connected” only confirms WAN connectivity, not routability from outside. [Elektroda, waldemar.podgorski, post #16627158]

Why does my port scan say “Port 94 Timed-Out” after I map TCP/UDP 94?

Your scan times out because external hosts cannot reach your LAN host through the LTE network. The upstream translation blocks unsolicited inbound sessions, so the port mapping on the B593u-12 never sees the probe. This matches the forum test result for port 94. Consider VPN or a server‑polling pattern instead of raw port forwarding. [Elektroda, waldemar.podgorski, post #16627036]

How can I check if my LTE IP is truly public?

Compare the IP on an external site with the WAN IP shown by your router. If they differ, your carrier is placing you behind their gateway and you lack a public address. This simple check was suggested in the thread and confirmed by the mismatch example. [Elektroda, skoczon, post #16627059]

My router shows 100.82.16.121 but the web shows 5.172.255.71—what does that mean?

It means the router’s WAN IP and the internet‑visible IP differ, so inbound connections cannot find their way back to your device. Any port mapping on the router will fail for external tests. You need either an operator plan with public IP, a VPN, or a relay. [Elektroda, waldemar.podgorski, post #16627158]

Why does my IP camera work remotely while my ESP8266 server does not?

Your camera and the CamHi app both log into hipcam.org and exchange video through that cloud relay. No inbound port to your home is needed. Your ESP8266 service expects direct inbound access, which the LTE setup blocks. “The camera and the application connect to the ‘cloud’.” [Elektroda, Heinzek, post #16628547]

What’s the fastest workaround without changing my mobile plan?

Use a cloud/intermediary server. Point your client (ESP8266) to poll a variable or command file on your server and act on it. This turns the flow outbound only, which works through the LTE gateway. Increase poll frequency if you need faster reaction. [Elektroda, Heinzek, post #16629824]

Can a VPN make my home server reachable?

Yes. Buy a VPN with a public endpoint and have both the device and your remote client connect to it. They will meet inside the VPN, similar to the camera’s cloud model, bypassing the need for inbound ports on the LTE link. [Elektroda, Heinzek, post #16628547]

What APN should I use on T‑Mobile for external access?

Set the connection profile (APN) to "data" instead of “internet” if your plan requires it. Some operators tie public addressing or specific routing behavior to particular APNs. If your plan still lacks public IP, port forwarding remains blocked. [Elektroda, skoczon, post #16627059]

Is DDNS enough to reach my camera or server?

DDNS only maps a hostname to an external IP. If your device uses a cloud service like hipcam.org, DDNS is unnecessary for access. For direct hosting, DDNS won’t help if your carrier doesn’t provide a public, reachable IP in the first place. [Elektroda, waldemar.podgorski, post #16628513]

How do I test whether my LTE plan allows inbound access? (3-step)

  1. Check your router’s WAN IP in its status page. 2. Visit an external “what’s my IP” site and note the address. 3. If they match, test a forwarded port with a scanner; if not, inbound is blocked. [Elektroda, skoczon, post #16627059]

What’s an effective polling interval for an ESP8266 control loop?

The thread example used hourly polling and found it limiting. Increase the frequency until latency meets your needs, balancing server load and data costs. If traffic is light, tighter intervals are fine. This pull model fits networks that block inbound sessions. [Elektroda, waldemar.podgorski, post #16628649]

Any hidden gotchas with cloud relays or polling?

A relay centralizes traffic; if the service is down, remote access fails. With polling, commands apply only at the next check, so control latency equals your interval. As one expert noted, “All data flies through the server,” so plan for that dependency. [Elektroda, Heinzek, post #16629824]
