Q: Why doesn't my web site's port forwarding work?

Hi I think this is the right site to post this on so I will! I have made a website on my Raspberry Pi that works perfectly over the local network. It is running on lighttpd. I have setup a dns on No-IP (pumpkinprograms.ddns.net) and I know it works because I use it for other things. Finally, I po...

AFH

You have other services set up on the same IP: do they work? Are there any firewalls involved?

Jonah Fleming

@AFH yes the FTP server does work and so do other things. I have the firewall setup but that is because otherwise port 80 and 443 go to the router homepage and another router page.

AFH

Have you tried mapping a different port, as in FTP and SSH (at least, I think that's what the line above is)?

Jonah Fleming

@AFH Sorry I don't get what you mean. Do you mean put the server on port xxxx instead of 80?

AFH

Yes, precisely.

@AFH BTW I am testing out the server on an iPad with hotspot to test it and I get the error network connection lost

AFH

And the iPad works on the internal network?

Jonah Fleming

Yes.

Sorry I had to go and take my dog for a quick walk.

AFH

Can you check the logs on the web server to see if it receives any contact from outside? Maybe check the router logs as well, and compare the failed web access with the successful FTP access.

Jonah Fleming

Ok I will try

Can you please go to pumpkin programs.ddns.net:1000 and test it? I checked on canyouseeme.org and it worked but with 80 open it didn't work... Firewall issue?

The log is very confusing...

I have a feeling it is my ISP. I will check. Thanks for your time!

Port 1000 was fine, but not port 80. Maybe you're right about your ISP - maybe they don't like customers running web servers.

Jonah Fleming

I just looked it up and they say that they don't let people run web servers. Grrrr. Do you know any way around this?

so you saw my website?

AFH

Yes, I did see it. I guess you have the work-round, though I'd be careful: if they realise what you're doing they may cut you off for breaching of your terms and conditions.

Jonah Fleming

Cool. Thanks

AFH

I'm going to bed, now. If I can help further, please contact me and I'll try answer you tomorrow.

I notice that there have been a couple of up-votes for your question, so there is some degree of interest in it. Since we have reached a conclusion of sorts, I think it ought to be documented, so I propose to post an answer, but I'll leave it for some hours, in case you have anything else to add.
