configure specific port range
I am newbie to Linux using RHEL 6.2 version.
My application is using port range from 11000 to 11100.
Only some of the ports between this range are available but I want range from 11000 to 11100 should be opened.
So that, I want help from any body about how to configure the specified port range into iptable.
I did some change in tables using below command :
1. #iptables -A INPUT -p tcp --destination-port 6881:6999 -j ACCEPT
2. #service iptables save
3. #service iptables restart
but after restarting the iptables this entry is not reflected into iptables.
Please help me.
