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 port
17TCP & UDP port
19TCP & UDP port
1900These 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.
