| If you can't connect to your server on some ports it's most likely due to the Linux Firewall. We enable the Linux Firewall on all Virtual & Dedicated servers at the time of provisioning. By default ONLY SSH is allowed access while all other types of traffic, such as HTTP, MAIL, DNS, ICMP are dropped. We recognise that not all of our customers are technical enough to configure the Firewall or may not realise the importance of turning on the Firewall, and as a result we ere on the side of caution by enabling it from the word go. Depending on the role of your server (web server, database server, mail server, etc) the first thing you should do is configure allowed traffic. If your server has a control panel installed such as Webmin, you can manage the firewall via the web console.
