    Apache isn't responding on http only in https

    I got a fresh install of Ubuntu + Lamp server but i can't make apache working for http. I've instaled ajaxterm and is working ok in port 443, listen for exterior conections.
    My problem is that i can't get Apache in http. It work ok in my local networks but not in exterior.
    Thanks for the help

    If it works OK on your local network, but not over the internet, then it must be a networking issue. Check the settings on your router, and verify your ISP allows servers on port 80.

    Yes, my isp alows trafic from port 80 because i've got another server runing apache but in windows. And my router setings is ok too.

    If apache is listening and responding on that port, and your router is configured correctly, then it should be working. Whether the request comes from the LAN or WAN, apache should respond the same. If you get a response from the LAN but not from the WAN, and you aren't blocking non-LAN IP's with iptables, then the problem isn't with the server.

    I've tried to change the port number to 8080 but it's all the same. Can i do something more about?

    Stick that machine in the DMZ temporarily and see if it works then.

    Post your config file so we can see if there is any errors...

    Thanks for the replies.
    Once again I've made a fresh install and it´s all the same.
    I can't get connections outside my networks to http, but I've installed Ajaxterm and i can access to https.

    I've already made the direct connection to the modem without the router and the result is the same

    # The configuration directives are grouped into three basic sections:           
    #  1. Directives that control the operation of the Apache server process as a

    #  2. Directives that define the parameters of the 'main' or 'default' server,  
    #     which responds to requests that aren't handled by a virtual host.         
    #     These directives also provide default values for the settings             
    #     of all virtual hosts.                                                     
    #  3. Settings for virtual hosts, which allow Web requests to be sent to        
    #     different IP addresses or hostnames and have them handled by the          
    #     same Apache server process.

    # of the server's control files begin with "/" (or "drive:/" for Win32), the    
    # server will use that explicit path.  If the filenames do *not* begin          
    # with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log

    Re: Apache isn't responding on http only in https

    Even IF it were a configuration error with apache, it would still give some response such as a 403 error. As I already said, unless iptables is blocking non-lan IP's, your server is working correctly since it works from inside your LAN. Apache doesn't drop connections from non-lan IP's. You have a routing issue somewhere.

    Just to be sure that you are in fact getting no response on port 80, post the output from running these commands from outside your network, or post your IP so someone else can.
    Code:
    nc -z -v [your ip] 80
    nc -z -v [your ip] 443
    Connecting to your WAN IP from inside your network is not always the same as connecting from outside your network, but since you said TCP 443 works and TCP 80 worked before, that probably isn't your issue.
