We've got JIRA setup on a VPS, which works fine for the office and even home connections. However, one of our staff members couldn't access JIRA from America. They can connect to the server just fine but it seems to be just JIRA that won't load; they get the default Plesk index page.
I've added port 8080 to the server's ip tables for good measure and even specified their public IP address for good measure.
Are there any other configurations that would block IP address ranges?
