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

I tried and it does not work
iptables -t nat -A PREROUTING -p tcp --dport 1000:2000 -j DNAT
--to-destination 192.168.1.100:3000 ==> Ok all traffic received with
destination port in 1000:2000 is redirected to 192.168.1.100:3000
but iptables -t nat -A PREROUTING -p tcp --dport 1000:2000 -j DNAT
--to-destination 192.168.1.100:3000-4000 ==> does not work : no
traffic is redirected
it seem a known issue : https://bugzilla.netfilter.org/show_bug.cgi?id=1501
