Blocked IP still has access to the server

Unread post by victor2306 »

Hi,

why an IP that is already blacklisted still can access the server and generate "Multiple failed logins"

what are your firewall rules?

Which ones? There are many firewall rules and most were generated by ASL.

I am not an expert, where should I look?

a couple of ways to do this:

# iptables -v -n -L | grep 'ip-address-you-want-to-look-for'

Or you can select the firewall option in the GUI and check the Input section

Also check the Blocking section in the GUI to see which IPs are currently supposed to be blocked

Also, if youre on a VPS you may have run out of iptables slots, in which case the VPS host will prevent you from adding any new iptables rules.You'll need to configure the VPS host to let you have more iptables rules.
