You remove the rule that accepts the established connection.

I have a specific rule for each host that is forwarded through firewall. 
If I want to allow the host, I add the rule in FORWARD chain:

ACCEPT     all  --  *      eth0    <ip_of_host>        
0.0.0.0/0          state RELATED,ESTABLISHED

When I want to stop them I just remove the rule. Even if the established 
entry appears and lingers in /proc/net/ip_conntrack, it can't go anywhere.
At least that's how it seems to work for me... Am I wrong??

Cheers,
Michael
