User Reviews

  • There is still some room for improvement but it already is a quality. Fantastic tool for network engineers.
  • Hi Guys and to ALL those in making GNS3 great, A very nice tool this gns3 is, kudos all round. I have a few feature requests that should be easy to implement: 1 - Please add a 'Close Project' button as well as a menu item under the 'File' menu. REASON: in general closing something like a file or project makes more sense to the everyday user as we were taught this from the 1990's already... 2 - When a topology is made by dragging items to the screen, do not bind the gns3 version (2.1.21 or 2.2 etc. ) to the topology. Instead have a compatible window to state the version number compatibility. REASON: We share topologies between friends/programmers/consultants and not ALL of us prefer to use the latest greatest versions. It will be best to make the topology stand-alone item that can be exported/imported with ease across different versions of GNS3 3 - Please add a feature to the 'Snapshots' window to: --edit the name of the snapshot -- 'Lock' & 'Unlock' the snapshot to prevent ANY changes to it -- 'Autoload' a snapshot upon project opening -- 'Update' a snapshots' items in the window after a config change was done so the user can open the 'Snapshots' window, select the relevant snapshot and click 'Update' . The 'Delete' and 'Restore' features works just great. Thanks Guys, hear from you soon JM
