Synopsis:
This guide contains instructions for removing a blocked IP address from within Config Server Firewall

Prerequisites:
1. You must have an active cPanel/Linux Virtual Server with CSF installed.

How-to Steps:

1. Login to cPanel and browse to here: Home » Plugins » ConfigServer Security & Firewall

2. Click the 'View IPtables Rules' button. (This will show all of the block and allow rules enabled in CSF)

3. Verify the IP you need to unblock is listed (Ctrl + f).  It will be contained in a line similar to this:

45    1437 85804 DROP       all  --  !lo    *       123.123.123.123      0.0.0.0/0 

4. If the IP is listed, highlight and copy it (Ctrl + c) and then return to the previous screen (Home » Plugins » ConfigServer Security & Firewall)

5. Paste the IP into the Quick Unblock field and click the 'Quick Unblock' button.  The IP has now been removed from the blocklist.

Optional: If you would like to whitelist the IP (permanently) on your server, paste it into the Quick Allow field and click the 'Quick Allow' button.
