is it possible to use iptables to define a rule to make a port forwarding of a range of ports For example : iptables -t nat -A PREROUTING -p tcp --dport 1000:2000 -j DNAT --to-destination 192.168.1.100:3000-4000 so traffic for port 1000 will be redirected to port 3000 and traffic for port 1000+n ==> 3000+N
