I am confused to why this has started to happen. On my local network, if I click 10-20 apache/http links my server will decide to add me hosts.deny file and block me on iptables.

Its not just apache, it seems to happen with any kinda of traffic, that comes in on a flood method. Like I use subsonic, if I change tracks 10-20 times, it will do it.

I would assume I have some sort of firewall which is sitting on the server which is doing this. However I do not have fail2ban or any denyhosts in /var/lib.

I cannot work out why I keep getting added to hosts.deny/iptables.

Thanks
