And I propably need same for IPv6 too. I'd like to this with route instead of firewall 'cause this is temporary and kernel of that computer

It's better to use a firewall than routing to block traffic, but you want to use one of these flags:

     -reject    RTF_REJECT     - emit an ICMP unreachable when matched
     -blackhole RTF_BLACKHOLE  - silently discard pkts (during updates)

Something like:

route add 192.168.10.1 localhost -reject

Oh. And if I add this route, how can delete it later?

route delete 192.168.10.1
