How to unblock an IP address from WHM (Crucial VPS)

To make it easier to get in touch with us, from the 24th of March 2016 all support tickets will need to be submitted from your Crucial Control Panel.

NOTE: If your IP is blocked, note down your IP (you can find it using whatismyip.com) then tether your phone's internet connection to your computer (your ISP should be able to assist with doing this). You'll now have an unblocked IP address that you can use to log into your server and unblock your main IP.

 

NOTE: If you're on a Managed VPS you won't have access to the WHM firewall by default. However, you can submit a support ticket and request access to it.

 

Step 1 - Log into WHM

 

Step 2 - Find and click on the ConfigServer Security & Firewall tool

 

 

NOTE1: The process differs slightly for Control Panel/Blaze/Barebones and Managed VPS products. I'll list both processes below:

Step 2 - Find and click on the ConfigServer Security & Firewall tool

Step 3 - Find the Search for IP section, input the blocked IP address and hit Enter or click on the Search for IP button

 

 

If the IP is blocked you'll see this screen. Take note of the reason for the block. Click the green Unblock button to unblock the IP

 

 

Step 4Once the IP is blocked you will see this screen

 

 

Note that this doesn't stop the IP from being blocked again. To find the exact reason for the block you will need to SSH into the server as root and run the corresponding commands:

 

Failed IMAP/POP login: zgrep ip /var/log/maillog* | grep fail

Failed SMTP login: zgrep ip /var/log/exim_mainlog* | grep fail

Failed cPanel login: zgrep ip /usr/local/cpanel/logs/access_log* | grep fail

Failed FTP login: zgrep ip /var/log/messages* | grep fail

Failed SSH login: zgrep ip /var/log/messages* | grep fail

 

Managed VPS 

 

Step 3 - The Firewall tool for Managed VPS looks a little different to the others. Input the IP in the Search for IP field and hit the Search for IP button

 

 

Step 4 - Note down the reason for the IP block and hit Return

 

5 - Input the IP address in the Quick Unblock field and click on Quick Unblock

 

 

6 - You will see a screen like this telling you that the IP was unblocked

 

 

If you can't determine exactly why the IP was blocked from the error code provided after hitting the Search for IP button, send that error page to us in a ticket and we'll be able to find the exact reason for you.
