I have bought an internet connection from Elisa/Saunalahti and a Huawei B315e router, and everything works fine, except from port forwarding. I have opened port 82 where I run my web server on my local machine, and I can not connect to it from my public IP address. The port is accessible through localhost:82, 192.168.100.10:82, but not ip:82. I have verified I use correct internal IP address for my machine, correct port and the settings should be fine. I also know Windows is letting me access my port, as I had the exact same configuration before I moved with an Inteno router I used then. I also have the Saunalahti public IP on my account, so I should be able to get an IP address to use for connecting. I have posted a reference to some of my settings below:

Maybe Saunalahti is blocking ports below 1024?

You could try adding additional port mappings on Huawei's virtual servers lists to check this out. For example WAN port 8000 to LAN IP 192.168.100.10 LAN port 82 and/or WAN port 8080 to LAN IP 192.168.100.10 LAN port 82.

Then try downforeveryoneorjustme.com again using all the ports you have configured.

BTW, have you confirmed that your WAN IP address as shown on Huawei's web interface is really public? Be aware that besides traditional 10., 172.16. to 172.31. and 192.168. private address ranges, 100.64. to 100.127. is used for carrier grade NAT.

Getting a public ip address with Elisa / Saunalahti mobile data requires both that you subscribe to the service and you have configured your router to use access point name (APN) internet4.

Did you try to access your server using the public ip address while connected to same Huawei B315e as your server is connected to?

If you did, it may be that B315e NAT fails to route to the public ip address of the NAT router from the internal network. This a common problem with several NAT routers. You may also check the settings of B315e if there is a setting for this, like allow NAT loopback or allow WAN loopback.

Please check access to your server using another internet connection. If possible, use one that is not Elisa / Saunalahti, because there are routing problems between Saunalahti customers, too.

The settings on the two screen captures you attached look ok.
I used the same local computer to check the address, as well as now isup.me and downforeveryoneorjustme.com to check what they say, and they report it is not accessible. What result I get by chrome is "ERR_CONNECTION_REFUSED". I neither can find any setting about NAT loopback, however I have setting like so: http://i.imgur.com/EP52Xwn.png

I tried to configure the server to port 8080 for both WAN and LAN (8080 -> 82 did not work for some reason), and yet it works only with localhost and 192.168.100.10, but not with public IP. I have used whatismyip.com to verify my public IP address, and it is 80.186.x.x. I do not see any IP addresses in my Huawei control panel. downforeveryoneorjustme.com also reports it is not working either. From what I can tell I am subscribed to the service and have internet4 enabled.

EDIT: I tried pinging myself with cmd, and my public IP times out... Localhost and 192.168.100.10 still do work fine. There's clearly something funny going on but I cant tell whats up
I have the exact same problem with my Elisa-mobile network router B315. I have done all the above setup, but the router does not respond to it's public IP address and no Virtual Server port-fowarding does work to LAN services ( I have tried port numbers < 1024 and above that, but nothing helps.

Only thing that I am not sure about is that APN/Internet4 setting that I don't if I have it or not. What is it and how does one setup it. I am using the default Elisa-profile but that says in the APN section only Internet, nothing else. Is that or problem or what?

Unless I get this working I have to cancel my subscription and become a customer of some other operator than Elisa/Saunalahti where I can get this setup.

Internet4 is a public IP, which you can order as an extra service to your mobile broadband (opening fee 3,90 e and monthly fee 1,99 e). You can order it from your OmaElisa by following this route: from the left hand grey margin go to OmaSaunalahti -> select GSM-Liittymät ja Mobiililaajakaista -> Liittymät -> select your mobile broadband -> on the corner you'll find "Tilattavat lisäpalvelut" and "Julkinen IP-osoite 4G".

After you have ordered the public IP you need to change the APN to Internet4.

If you have problems with the ordering, you can contact us via private message with your personal details so we can get it for you 🙂
Thanks for an explanation on my connectivity problem. I'll contact you in PM so that we can discuss about my subscription details etc.

Cheers for now,

PS. I think I need to change to enterprise (yritysasiakkuus) customer cause this router and the www-services that I plan to host in there are in use and owned by our community / organization that providers them. I hope it is ok to change the subsription cause I didn't know that the public IPv4 is an extra service that needs to be purchased separately.
