🔹 Firewall & Port Settings #
A firewall protects your server from unauthorized access and malicious attacks by controlling which ports are open or closed. Proper configuration keeps your website and server safe.
1️⃣ Allowed Ports Overview #
Some ports are open by default to allow normal server and website operations:
| Service | Port | Purpose |
|---|---|---|
| HTTP | 80 | Standard website traffic |
| HTTPS | 443 | Secure website traffic |
| FTP | 21 | File transfer |
| SFTP / SSH | 22 | Secure server access |
| SMTP | 465 / 587 | Sending emails |
| IMAP | 993 | Receiving emails securely |
📌 Only these essential ports should usually be open.
2️⃣ Why Some Ports Are Blocked #
Ports are blocked to prevent hacking attempts or misuse:
-
Open ports = potential entry points for attackers
-
Non-essential ports are blocked by default
-
Examples: Telnet (23), RDP (3389), non-standard FTP ports
📌 Blocking unnecessary ports reduces risk and improves server security.
3️⃣ Requesting Port Access #
If you need a blocked port for a specific service:
-
Open a support ticket in the ecHOST Client Area
-
Provide:
-
Port number
-
Service name/purpose
-
Duration (if temporary)
-
-
Wait for confirmation from the server admin
-
Only approved ports are opened
📌 Avoid requesting unnecessary ports to maintain security.
🔐 Tips for Firewall & Port Security #
-
Keep only essential ports open
-
Regularly review firewall rules
-
Use SFTP/SSH instead of unencrypted protocols
-
Report suspicious activity immediately
