Block IPs from brute force hack attempts

Hello, is it possible to block IPs that attempt to access my server through brute force. Currently I manually add the IP address as a host address, add that name to the address group, which is blocked at the firewall. I would love to have this done automatically by my zywalls ( I have both the 50 and 20)
Is this possible?

Thank you

It's not possible on USG, but you may be able to do it on your server.
What kind of server do you have? OS?
Check out »www.fail2ban.org


I 'am running 2011 home server.
The windows firewall is disabled and I am using the firewall from AVG Antivirus Business Edition 2013.
I guess even some way to pull out X failed attempts and throw it into a txt file without me having to scan my eventlog would be great. My servers seems to be popular with Chinese and Russian brute force attacks.



This is up to your server to do, since the ZyWALL do not know if the connection was rejected or not.

But when you got a text file of IP's you want to block, writing a script that updates your firewall rules should be quite trivial.

ISA [Internet Security and Acceleration Server] is a HIGH end product that offers a wealth of features and capabilities --- YOU cannot compare ISA server to ZyWALL USG regardless of model --- ISA server will be superior in every category -- but supporting ISA server is far more complex based on how many other "services" it compliments especially in the world of Microsoft integration. Most people here are Linux or Nix oriented and the ZyWALL USG line suits most people who are in love with the nix world. That is not to say that the USG line cannot work nicely in the Microsoft world --- it does --- but does not have the rich capabilities offered by the Microsoft security solution. TMG and UAG now replace ISA and for those in the know TMG is very expensive.

There is no reason in the world why you cannot keep using ISA server -- its still relevant regardless of the fact that its no longer supported.
