Server won't let traffic in

[OR83]

I'm having trouble with my server as it won't let any outside traffic in. I did port forwarding on my router I added the default gatewat as 192.168.1.1 and netmask as 255.255.255.0 nmap says some ports are closed but on the server says ALLOW ANYWHERE.

Run this please:

sudo iptables -L

sudo netstat -nlpu

Can you post the output of:

sudo iptables -L -v -n
sudo netstat -plunt

We need lots more information to be able to help.

What traffic are you trying to send to the server - what protocol?

What makes you say it "won't let traffic in"? How do you try to send traffic in, and what happens?

Please try these two commands and post the output:

netstat -lntu
sudo iptables-save -c

EDIT: Ooh, looks like I'm late to the party. Got distracted while answering.

SSH, HTTP,HTTPS,FTP, MySQL those protocols. I'm using a service like DynDNS because my ISP won't give me a static IP address my cousin says the page won't load

[OR83]

the link is http://oscar080483.no-ip.biz he says it won't load but when I ping it it gives me replies I'm not sure if it's because I'm on the internal network or what it is

[OR83]

there's nothing on the link other than the default apache server page.

That doesn't really tell us anything about the server itself.

Your cousin is right, it doesn't open.
Give us the results of the iptables and netstat commands posted earlier. That will help with more info.

Another reason is that the ISP might be blocking port 80 to prevent people running web servers at home. Did you verify it doesn't block it?

here's some output
