I'm in the process of setting up a new instance of ServiceDesk Plus, and an interesting scenario has come up that I have not run into before:

 

A non-technician user is a member of a CAB and selected as an approver for a change.  This user is offsite and disconnected from the corporate network.  They receive the Request for Approval on their mobile and wish to submit their response without returning to the office or remotely connecting to the corporate network.

 

Can this be done without exposing the ServiceDesk Plus server to the general internet? 

 

Any method of accomplishing this is fine, as it is a new deployment and users will be trained as needed.  I really don't want to expose the server to the outside world, as it then comes into deeper scope for our security team.

 

Thanks.
