IPrule to disallow all out going connection
 

I want the IPtable rule for below request..


Configure the system firewall to disallow all out going connection unless they are already established. And all incoming connections unless they are already established or on the RDP port. This should create a system that can only be accessed by RDP and cannot talk to the outside world otherwise.

Thanks,
