Greetings all--been using the product for a while now, and am trying to find out if anyone has any 'hacks' to handle a problem. I'd contacted support a while back, and they indicated there was no way to do what I need.
Basically--I've got three hosts in my DMZ, and some lusers on the net who show up in the logs almost daily--one brute forcing an ftpd, another always trying some new random web exploit. They're probably just robots with some kid behind them--but the ISPs have been wholly unresponsive to requests to handle it--and I'm sick of seeing a fresh ban in my logs every time the old one expires.
I've got client software running on the hosts in the DMZ that automatically bans for such attempts--but the point at which I'm aware of two domains to the point where I can recall their admins address of the top of my head, I'd like something more permanently extreme--ideally the ability to ban an address or subnet for a specified period of time (say a year) entirely from all networks behind the ASG (could not care less if a few thousand people in Kentucky can't get to the website)
The closest I can think of is the familiar iptables command...
"iptables -I INPUT -s $HOSTILE_ADDR -j DROP"
but of course, the first thing the system does when you login is warn you that making such modifications can void the warranty so I haven't taken that route... and it would be nice to have this expire eventually.
Anyone have any experience or suggestions? I realize I could create a new network, and then drop draffic from that in the packetfilter...but that strikes me as not scalable for a host/network I just want to blacklist and forget about for a while.
Regards,
