I have cisco router connected to internet with no firewall.I want to allow internet connection for internal user and only easy VPN connection(using VPN client) from outside to internal network ,,how I could acheive this????
It's not administratively shutdown but it is in effect shutdown as there is nothing connected to it.
However the big difference is that if it is administratively shutdown and someone connects a UTP cable into it then it will stay down.
If it is not administratively shutdown and a cable is connected then it may well come up.
