Bloking access to certain host/ips to an application in asm

Hello group,

 

 

I will like to know if, at ASM policy level, it is possible to block access to a certain range of ip address/host. I ask this because we need to filter the acces from certain Internet ips to only be allowed to access some applications, and i think this would be easy made with an asm policy, however I cant find the way to make this, so, it is possible? or the only way to make this is by an iRule?

 

 

Thanks you in advance a best regards.

 

 

 

Miguel.
