    NetVanta 3430 block .cn domain

      I implemented a filter policy on the 3430 firewall to drop connections that are trying brute force attacks on our servers. Even though I can block by subnet I was wondering if it would be possible to do it by domain instead. I know we should not expect any connections from .cn, .ru, .il, etc and it would be much easier to block at that level then waiting until a new attack from a new network in .cn shows up so we can block it.
