Firewall IP Block

A firewall is a crucial security system that protects your server by blocking unauthorized access while allowing legitimate communications. We utilize ConfigServer Security & Firewall (CSF) to enhance server security by blocking IP addresses exhibiting suspicious behavior, such as repeated failed login attempts.

Common Issues

If you find your websites inaccessible and are unable to reach services like Mail, Web, FTP, or Control Panel, but others can access them, your external IP address may have been blocked by our firewall. You might encounter messages such as "server connection timed out," "the site cannot be reached," or "the connection was reset."

Initial Steps

1. Check Server Status: Visit our status page to see if there are any known technical issues.

2. If the server is operational, your IP might be blocked.

Frequent failed login attempts can lead to your IP being blocked.

Causes of IP Blocking

1. Excessive cPanel Login Attempts

If you fail to log into cPanel, avoid making multiple attempts. Use auto-login options in your Verpex account or refer to the login details in your Welcome Email. If needed, reset your cPanel password.

2. Email Connection Issues

The firewall also protects access to mail services.

• Webmail Access Blocked: If you can't access webmail, your IP may have been blocked due to failed login attempts.

• POP3/IMAP/SMTP Issues: Incorrect login credentials can cause repeated access attempts, potentially blocking your IP. Ensure your email client settings are correct.

3. FTP/SSH Login Failures

High numbers of simultaneous connections from an FTP client can trigger a block. Adjust your settings in clients like FileZilla:

1. Open FileZilla and go to Edit -> Settings.

2. Select Transfers from the left menu.

3. Set Maximum simultaneous transfers to 3 or fewer (1 is recommended).

4. Incorrect Email Client Settings

Remove and re-add the email account if you're experiencing setup issues.

5. Failed Web Page Logins

Ensure you are using the correct credentials for any authentication forms or secure directories on your website.

6. Repeated Incorrect WordPress Logins

Attempting to log in to your WordPress admin area with incorrect details can also trigger a block.

7. Unauthorized Country IP

For security reasons, IP addresses from certain countries are blocked.

8. Port Scanning

Attempts to scan server ports are flagged as suspicious. Make sure your clients are not configured to do this.

Quick Fix for cPanel IP Blocking Issues

If your IP has been blocked, you can request support to unblock it. Open a support ticket and provide your IP address using a tool like whatismyip.com.
