I've used ISPConfig for some time, and recently I have noticed that for some reason I keep finding myself unable to access the ISPConfig control panel at port 8080, and also other services like UnrealIRCD unable to be reached at port 6667 etc.
Web services and other services (mail etc) all seem fine when I can't access these others.
I've noticed that the only way I can seemingly access these services on port 8080 and 6667 is by logging in remotely with SSH and telling IPtables to start accepting stuff on these ports again.
I kinda know my way around the basics of Linux and managed to figure out that the command:
iptables -I INPUT -p tcp -m tcp --dport 8080 -j ACCEPT
iptables -I INPUT -p tcp -m tcp --dport 6667 -j ACCEPT
will fix my access to the ISPConfig panel.
However, some time later (haven't worked out how long exactly) I find that I can not access it again, and must issue the same command in SSH to gain access again, which is getting frustrating now.
What on earth keeps resetting iptables (at a guess, I'm not sure exactly what it is doing) and blocking my access to these ports?
Many thanks for your help
