How can i close connections from a particular IP with immediate effect after i dropped it using iptables. Still there are lot of connections in state FIN_WAIT1..
Maybe you should rather use DROP instead of REJECT in your iptables
rules? Just a thought.

No ... It has nothing to do with REJECT/DROP rules I think you should check the following values:

sysctl -a | grep fin_wait

On my machine the value is
net.ipv4.netfilter.ip_conntrack_tcp_timeout_fin_wait = 120

Decreasing the value may help solve your problem.
Check it out ...
