Cannot block an IP – whitelist alert but NOT on whitelist

    I am using Wordfence v.5.0.6

    I have an automatic block set for invalid logins. When I receive the alerts via email, I log into the site and manually block each one. Yesterday, there was a large flurry of attempts to log into the site with user: admin

    I was able to block all of them (then permanently blocked them) except for 172.20.9.53.

    When I try to block it, an alert appears that the IP address is whitelisted. However, I only have my own IP on the whitelist.

    A tracert and ping against IP 172.20.9.53 only yield timeouts.

    Using phpMyAdmin, the record for whitelisted in the database table for the configuration shows a blob, so I cannot delete that IP. Should I delete the record and then re-enter it?

    Looking at server logs next for more clues and will followup with what I find.

    Hi,

    That address is a private address which is non-routable on the Internet. What this means is that it’s from your hosting provider’s own internal network. You can read more about the 172 range here:

    https://en.wikipedia.org/wiki/Private_network#Private_IPv4_address_spaces

    We don’t allow you to block this to protect you from blocking network devices on your internal network.

    Hi, I have exactly the same issue. WP version 3.9.1 and Wordfence v5.0.7.

    I have had a dozen or so invalid log in attempts from 192.168.0.21 using various incorrect usernames which I cannot block as it says it is whitelisted – which it is not in in Wordfence options. Looks like the same issue as above. So we can’t block someone using these IP’s even though its an obvious hack attempt?

    Is there anything we can do?

    Thanks

    Rick
