I quickly tried setting up something on port 80 the other day and the
new modem/router (4200 ohio) wasn't open on port 80.
Didn't matter that much, was only testing something, but it's a bit
bullshit. You probably have to call and ask.
Wasn't an issue for me in the past. Tried setting up my web server again and
no go. Had to redirect to an alternate port.
