Agree with David.. If it is 6.3 and less, you can use my solution, if it is 7.x or 8.x, you can use no nat-control.. but im not really convinced with nat-controls.. by statically defining no-nats, the administrator always has the control of what traffic goes through the firewall, without nat, which is critical to his network.. If by default, all traffic is allowed, isnt it a security risk ? and if there is no access-list on the inside network, then it will be a major mess !
