It's a new installed server following perfect debian 5 setup with ispconfig 3.
In my case I was thinking it could be related with openvz (this server is a vps), but amcom told he is not using a openvz server... It's true that the server also has installed webmin, but if I'm not wrong webmin doesn't confgures firewall rules when installed...
Related with webmin, amcom, do you also have installed webmin?
By the way, if it helps I could post my iptables rules.
