Permanently block an ip after X amount of login failures?

Hi,

 

     I am struggling to find a solution to do the following:  Permanently block an ip after X amount of login failures?  I know it sounds simple, but, maybe someone can give me an example.  I don't want to block a range of ip's, just a specific one after X amount of login failures.  I wasn't sure if this is an EEM script that has to be created or something else?  Also, this can be a login that was tried after X amount of tries OR a login failure using different key words.  Basically, I am trying to keep out some of the crap coming from China and so on......

 

Thanks for everyone's help.

 

Cheers.

 

Jason

Hi,

 

     Sorry, I forgot to mention it's a Cisco 3825 router.  We don't have a firewall solution yet.  I just need something in the mean time.

 

Thanks.

Jason
