NetSim License TypeDongle and MAC Based Floating License



NetSim licenses can be accessed remotely over the internet with a VPN connection to the institution network in which the license server is on. Note that there is no limit/restrictions in terms of software installations. Any number of software installs can be done. The number of machines that can simultaneously use NetSim is limited by the number of licenses your organization has purchased. 

A VPN (virtual private network) connection is simply a tunnel on a network, usually via the internet. If a machine is remotely connected via VPN to a company network then it should be able to contact a license server and check out a license.  The remote machine will be able to use the license as long as it remains connected via VPN.
