Abaksoft Posted April 4, 2023 Share Posted April 4, 2023 Dears, 1. To manage an unigui home server, it can easily do like this : http://forums.unigui.com/index.php?/topic/5019-a-smart-home-server-100-free/ It is possible as far as your company ISP (Interner Service Provider) provide you a private IP adresse. This adresse is when you ping for example : myipadresse.com Note that major ADSL provide you a 24h private ip adresse. 2. Now, what about a 4g Router with SIM card. Pros : • These rooters are faster in upload and download then adsl line classical routers. Yes, they get internet from a SIM card, just like a mobile phone. • No need a fixe line phone. Take your rooter anywhere. Cons : The problem is on ip adress. The mobile internet method gives you a shared public IP adresse wich is not yours. Even if you find an other private IP adresse on your router, you can not access your home server. https://h685.co.uk/port-forwarding-doesnt-work/ Question : Has anyone find a workround to ping these 4g sim card rooters ?

Thx Hi, 10 years ago I had a similar problem with a client and server with dynamic IP addresses. I created 2 solutions: 1. On the server side, I created a server application that checks every 10 minutes (per user settings) what the public Ip address is and stores this information in a file on an ftp server. And on the client side: when you start the client application, it first reads the server IP address from the ftp file and then starts working with new IP address. On Client side I start from Bat file application with new IP settings ! 2. Another solution is with a UDP server and a client that looks for this server at startup and asks what its external IP address is. Hope these ideas help Some routers have settings to create an internet name in a dns server and then you can look it up by that name. Maybe yours has such settings.

I know these technics (even DNS embeded on router, also listning no-ip company and dynu.net ). The problem with the 4g routers sim card is you can get this public ip but it's not yours. It's a shared ip for 250 users. You can read : https://h685.co.uk/port-forwarding-doesnt-work/ Quote Link to comment Share on other sites More sharing options...

Did You see this proposal: https://superuser.com/questions/1690878/reach-ports-inside-a-lan-behind-a-4g-connection-from-outside "You can use VPN that supports port forward. But an easier alternative might be to access your streaming server via IPv6 - assuming you get one assigned by your ISP and your router supports it. If IPv6 does not work, there are two work arounds (not just VPN):" Quote Link to comment Share on other sites More sharing options...
irigsoft Posted April 4, 2023 Share Posted April 4, 2023 or this: https://community.spiceworks.com/topic/2273503-switched-to-4g-router-cant-connect-to-home-server "I finally managed to fix it. Here's the solution: I had to set the APN settings to my internet providers. (I asked the technician what to set it to) There was no port forwarding within their network (I guess that depends on what internet provider you have and what they allow)."

Really appreciate your help I finally contact my ISP, and they suggest me a solution. "You need a Static IP adress and for this if you want to use your 4g Router, we have an Offer named : M2M" Oh Yes, i said....Machine to Machine (M2M). Today all ISP have this offer. The only Cons, is the speed (lower Upload, lower donwload) it's only for communicating with machines over internet (Camera, watering tap, Robots, ...) I will buy a SIM Card M2M tomorrow and will give you feedback to communicate with my Unigui App. Best Regards Quote Link to comment Share on other sites More sharing options...

Don't lost your time. M2M sim card not work in a classical Modem 4g. There is no signal, no internet ! M2M Sim Card is only for specific devices like GPS, camera,... Conclusion : Stay with your classical ADSL line for a home server. 1 Quote Link to comment Share on other sites More sharing options...
