The last port which is globally opened for outgoing connections on our shared servers is 30000. This port is used by the Canada post shipping module, which is available for scripts like osCommerce and CreLoaded. The module establishes connection to the IP 66.110.6.131.

If you need another outgoing port to be opened (for example for game servers or shoutbox modules), please post a ticket in the SiteGround Help Desk->Get Support->Port Opening Request. Enter the destination IP for which you wish the port to be opened and the corresponding port number.

Due to the SiteGround security policy, custom incoming ports can not be opened per customer request on our shared servers. If you need incoming ports to be opened, please consider an upgrade of your account to a dedicated hosting solution. There all the system resources will be solely reserved for your account and the server firewall will be altered per your needs.
