Hi,
As I mentioned in my previous mails, I use something like below to
redirect connections from outside to my internal machine.
# iptables -t nat -I PREROUTING -d <my_ext_ip> -p tcp --dport \
8081 -j DNAT --to-destination 192.168.0.16:80

But I want only say 3 connections allowed at a time from outside. How do I 
do it in iptables?  I am not getting the exact syntax.

Thanks a lot in advance.
With warm regards,
-Payal
