I've never actually made a web server until now. I set up a very very simple server which is running sinatra on my desktop. I used a website called "whatismyipaddress.com" ...

Why can't I access my web server by it's IP address outside my LAN
It works fine when I try to access it by its ip address on my LAN, and I was able to ping the ip address from one of my school's computers (which is weird considering they have a firewall which I was expecting wouldn't allow that.)
I have been spending the last couple of hours changing my router's firewall settings, and nothing seems to work. I have already set it so that it should allow web server access on port 80 (presumably it is talking about web servers on the LAN), but it still doesn't work.

It looks like you have opened port 80 but have you configured the router to forward the requests on Port 80 to your server? How you do this depends on the router.
You are usually looking for "port forwarding"

In such a case, I'd been looking at the firewall. Either on the router or the server.

I've already checked the firewalls on my server (iptables, and ufw), and I checked the router's firewall and I didn't fully understand it but I think it allows for web servers.
my router's port forwarding looks like this:
I've got it's "SPI firewall" (whatever that is) disabled.
Also I have it set to filter "IDENT (port 113)" (which I don't know what that is).

I see you've also configured ports 21 and 23 to be redirected. Can you connect to either of those ports, or are they inaccessible as well?

If you have a dynamic address from your ISP, its possible that the address has changed. Is that router the only thing on your network? Your ISP give you a router/dialer?linux user # 503963
