Hello. Over the past few weeks, I have been attempting to host a web server on my Raspberry Pi 3B. I got everything set up, and I can access the site from my internet connection, but I cannot figure out how to set up the port forwarding to make it public. Can anybody suggest m an answer to this question?
You can obtain the model by accessing it with the AirPort Utility. Regardless, are you looking for assistance in how to configure port mapping your web server with this base station? If so, then the following user tip article should get you started:
After reviewing it, if you still require further assistance, please post back.
Ok, thanks. If you didn't before, I would like for you to run the traceroute command while SSH'ed into your RPi. You don't need to post the results, but the first two lines should match those when you ran it before. If you already ran it from the RPi, you can ignore this request. I am, of course, assuming that you normally work with the RPi via the DietPi's console.
If the results are the same, then the issue is something is blocking inbound requests over port 80 or the mapping it not set up properly. It may also be possible that your ISP IS blocking port 80 on your WAN-side to prevent you from running a local web server.
How can I check the model?
Open AirPort Utility on your Mac (Finder > Applications > Utilities > AirPort Utility)
Hold down the option key on your Mac while you double-click on the AirPort Extreme
The Model will be displayed at the top of the list of information about the AirPort Extreme
The airport is the main router
To check if the AirPort Extreme really is the "main" router on your network.....
Click the Network tab at the top of the AirPort Utility window
Note the setting for Router Mode
If it is DHCP and NAT, then the AirPort is acting as the router for your network
If the setting for Router Mode is Off (Bridge Mode), then there is another device acting as the router for your network.....likely the device that you call your modem.......since many modems also act as routers.
Yes, from your computer. Once you do just note what IP address is shown and report back, whether or not, it starts with 192, 172, or 10. Again, please don't post the actual full IP address.
I can say that the Tesserax guide.....Method 3......has been successful in allowing me to access hard drives and cameras connected to my router from a remote location over the Internet......most places that I've traveled in the world. Sometimes, I cannot connect because the local ISP or local router at the location will not allow this specific type of connection.
As Tesserax notes, the guide is there to get you started......not provide specifics for something in which we have no details.
Can you provide a link to the instructions from the setup guide or manual for the RPi?. In particular, we don't know whether port values are required for the remote access setup. We need specific values for the requirements of your device.
Public UDP Port
Public TCP Port
Private UDP Port
Public UDP Port
In addition, we need the specific method that your device requires to allow remote access using the Finder > Go > Connect to Server commands
Example.......afp//:98.76.543.21:8888......which is the public IP Address that has been provided to your AirPort router along with the specific port to be opened.
I have not used the RPi and do not know whether afp protocols would be correct for your device, but another user might. If your device requires smb protocols, that will likely affect things as well.
Even when we have the port settings and remote connection details, some ISPs will block certain ports from being used on their service. For example, when I needed remote access from the Internet back to devices on my network , I had to change my ISP.
Finally, setting up Port Mapping or Port Forwarding is never an exact science and few situations are ever the same. Often, the assistance of an IT Professional on site at your network location may be required to get things set up correctly.
We'll try to help, but without knowing exactly "how" you are trying to connect now, we can't even begin the troubleshooting process.
Did you not get a setup manual or a setup guide for your product?
Port 80 is used by any number of other applications.....like Mail.....so you will likely need to use a different port for the RPi.
My former ISP insisted they were not blocking any ports, but when I tried a new ISP, things worked perfectly on ports like 8888 and 548.
I don't have an RPi here to test, so I'm probably not going to be able to provide much in the way of detailed help. Hopefully, another user who has the same device as you will see this post and will try to help.
What feedback have you received from RPi support?
The RPi is not specifically meant for web servers, it can be used for whatever you want, so it does not have a setup manual. I followed a tutorial, and I could link it if that would help anything. The previously mentioned tutorial, as well as a few other sites, have stated that you should use port 80 if you want to open to HTTP, which I do want to. Also, my bad, there should be no UDP set, but TCP should be open to 80. Here is the guide that I found: https://portforward.com/ports.htm
A lot of products assume that you are using a router with a feature called UPnP......Universal Plug and Play.....which opens required ports automatically on the router. Apple does not support UPnP, so you have to manually enter all the port values required.
My opinion is that it will take more than Port 80.....which is already likely in use by another application.....to get the RPi working. I could be wrong, so I'll let the RPi experts speak.
Tell us a bit about your network. For example, is your AirPort Extreme base station your "main" Internet router? That is, is it connected directly to a simple modem (not a combination modem/router, or gateway device), by Ethernet? Which exact model is your base station. Does your ISP provide you with a static Public IP address or a dynamic one?
Do you have your RPi configured with a static local IP address? I am assuming that you can access its web server from within your local network ... correct?
The airport is the main router. How can I check the model? I believe that my ISP provides a static IP address. I have configured the RPi with a static local IP, and I can access it within my local network.
What do you mean by the setup guide for the RPi? The port values are supposed to be 80 for everything. What do you mean by "specific method that your device requires to allow remote access..."? I believe that my ISP keeps every port open, as I have called them and they confirmed that.
Tesserax has already provided this information for you in his guide. Where in the detailed steps are you getting stuck?
Hopefully, Tesserax will be back online soon. I will let him reply, but he'll very likely need to know what other ports other than 80 are required to do what you want.
I followed each step of the guide, and I can get to the end, it just does not change anything. I type in the IP address of the RPi while not connected to my internet, and it will not load. If I connect to my internet and type in the IP, it loads perfectly. I do not know what other ports besides 80 I would need.
FWIW. I don't run a web server on my RPi. Instead I use them for things like Pi-hole, AdGuard, and the UniFi Controller ... so I cannot specifically test for you. Also none of these apps require that they be accessible from the Internet.
Your comments confuse me. You stated that you can access the RPi from the Internet, but not locally. I would expect that to be just the opposite. Are you sure this is what you meant. That is, if you ping the local IP address of your RPi, if fails? Is your RPi a 3B or a 3B+ model? Which version of Raspbarian or other OS is it running? Do you have it connected directly to your router by Ethernet or to another Ethernet switch?
Ok, that makes more sense now. How exactly are you trying to access your RPi from the Internet? That is, are you going to a remote location, and then, try connecting to it? ... or are you trying to access it from your local network, but using your WAN-side IP address in the URL in a web browser?
