What Ports Are Blocked?
Published on: Mon, Sep 22, 2014 at 11:25 am EST
We block several ports that are commonly abused for DDOS attacks:
- TCP & UDP port 17
- TCP & UDP port 19
- TCP & UDP port 1900
- UDP port 53413
- UDP port 11211
These blocks are permanent, and cannot be removed.
The following ports may be blocked, depending on your account:
- TCP port 25 (SMTP)
- TCP & UDP port 137
- TCP & UDP port 138
- TCP & UDP port 139
- TCP & UDP port 445
You may request these blocks be removed by opening a support ticket.
