I've been searching, but haven't found this yet. Usually I'm good at "googling" things, but this has stumped me so far. Today's routers are more than powerful enough - could someone tell me which router firmwares will load "block lists" for blocking "bad" IP ranges? (Want to block IPs of known: malware/spyware sources, SPAM senders, "bot net" bots, anti P2P, etc.). Surely there must be some routers/firmwares which support this by now? I know that most router's firmware GUIs ("web interface") will have a page where you can switch between whitelist or blacklist and manually add IPs, but if you could at least load them from a file, or specify a host to download them from, that would basically do what's needed to have something like a "Peerblock" shield protecting your whole LAN at the router.
