What Ports Are Blocked?
Modified on: Fri, May 1, 2015 at 9:52 am EST
We block several ports that are commonly abused for DDOS attacks:
TCP & UDP port17
TCP & UDP port19
TCP & UDP port1900
These blocks are permanent, and cannot be removed.Depending on your account, outbound SMTP (port
25
) may also be blocked. This block can be removed by opening a support ticket.
