    Server works on Lan but not over internet.

    My server was working just fine and after a reboot, it will work when I am here at home on my lan, but it is not accessible from anywhere else? How do I fix this? it was just running a couple days ago, it has to be something simple. I am running a router and haven't changed anything in the router and I am using virtual hosts and haven't changed anything there either. Strange.......

    Thanks,
    Dan

    What are you trying to serve? You mentioned VirtualHosts, so I'm guessing you are running Apache. Have you tried checking to make sure it is accessible from the outside by using something like http://canyouseeme.org/ ?

    I did a dig on it and it returned this:

    If canyouseeme shows the port is open, it could be a DNS issue, or you external IP address might have changed.

    Here's a dig from my site, for reference.

    charles@Thor:~$ dig charlesa.net

    It's timing out for me. I'm wondering if your ISP has started blocking port 80.

    Edit: what I'm seeing via DIG is similar to what CharlesA has reported seeing.

    Times out for me too, but I can ping it, so that sounds like that might be the case.

    hmmm strange. I have port 8080 also. I have no idea why it's not responding now. My external i.p. has not changed, and openport does not see my site either.

    I can access my site on my lan by using the domain name, so I assume that port 80 is not blocked.
