Not really sure if this question belongs here or in hardware, but here goes, anyway :-
Using "Realport Technolgy" and a DigiOne SP, I can 'pretend' that I have a direct connection from my PC to my serial port device. OK, I am actually connected over Ethernet, however does this mean that I can connect to any two Ethernet ports in the world, and still work. Or do I have to be on the same LAN/hub/switch.
If it is any 2 Ethernet ports globally, I presume there would have to be a setup procedure, to allow various firewalls and/or routers to be tunneled through ? Or worse still VPN's having to be setup.
Is this global setup a reality, as this is part of the requirement, or am I hoping for the impossible ? It would be a consumer that would need to set this up, not an IT dept/person.
Thanks for any help, even if it's saying this cant be done
