🔹 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.
