i have a iptable firewall installed on red hat 9.0.I wanted to allow a range of ports say 5000 to 5050 .I tied using 5000:5050 ,but it doesnt seem to work.Can any one help me out with the correct syntax.

iptables version is iptables v1.2.7a:

The command was

iptables -t filter -A FORWARD -s -p tcp -m state --state NEW -m multiport --dports 7000:7100 -j ACCEPT
