Does anyone have any experience with large block lists?
I am running an email server and get hit with brute force password attacks from IPs that are commonly found in blacklists.
Although the server features and is set up for automatic lockout of IPs that do multiple attempts at passwords, i would like to move this to firewall.
Does anyone have any experience in what kind of a hit on performance a 11k line blacklist makes to the router? The router is a RB3011.
